Lab Grown Diamond

What is Lab Grown Diamond?

As the name suggests itself, Diamonds which are produced with an Artificial Scientific Process in Laboratory are pretty much known as Lab Grown Diamonds.

Natural Diamonds on the contrary are created by Earth Geological Processes.

 

Other widely known terms / alias of Lab Grown Diamonds are as below.

  • Synthetic Diamonds
  • Man Made Diamonds
  • Cultured Diamonds
  • Cultivated Diamonds

 

 

Similarity

Lab Grown Diamonds are very much Similar to Mined Diamonds. They share same Physical, Chemical & Optical Properties with Natural Counterparts of Mined Diamonds.

 

Types

Principally there are 2 Types of Lab Grown Diamonds.

  • HPHT (High Pressure High Temperature)
  • CVD (Chemical Vapour Deposit)

Above are basically the names of technology through which the Lab Grown Diamonds are being produced.

 

 


 

Physical & Chemical Properties of Lab Grown Diamonds

 

 

The below are the basic Properties of Lab Grown Diamonds.

  • Hardness
  • Thermal Conductivity
  • Electron Mobility

If we compare with Naturally-Formed-Diamonds, by these properties the Lab Grown Diamonds are ranked higher regardless of the technology (HPHT or CVD) used to form them.

 

 

The below is the List of Conclusive Test as Proofs in order to identify Lab Grown Diamonds.

  1. X-Ray Diffraction Patterns

It identifies the Crystal Structure of Lab Grown Diamonds compare to that of Natural Diamonds.

  1. Chemical Analysis

To get results if Crystals were composed of Carbon.

86% Carbon & 14% Inorganic are standard result for Lab Grown Diamonds.

  1. Hardness Tests

The 111 Face of Natural Diamond is tested to be scratched as it is very hard to scratch so.

  1. Repeatability

In the company During Production number of Workers repeats the synthesis of Diamond on a separately. The Lab Grown Diamonds have to pass through these conclusive tests.

Lag Grown Diamonds get the Refraction Index Range of 2.40 to 2.50.

5 Isotropic Minerals (listed in Mineral Compilations) share the Refractive Index near this Range.

 

 

What are the Criteria of the Lab Grown Diamond?

 

There are a total of 5 Criteria for Lab Grown Diamond.

 

Shape

  • It defines the form of the Lab Grown Diamond.
  • It is basically viewed from above.
  • The Shapes of Lab Grown Diamonds carry distinctive Attributes.
  • However, it is up to our personal choice to like the beauty of any Lab Grown Diamond Shape.
  • Few Shapes of Lab Grown Diamond are as below.

o   Round

o   Princess

o   Radiant

 

 

Cut

Normally the Brilliance of the Lab Grown Diamond is defined by its Cut.

The Better the Cut of the Lab Grown Diamond the More it will sparkle as a whole.

 

 

Color

With the Lack of Color, the ColorGrade gets higher in general with respect to Diamonds.

The White Lab Grown Diamonds gets for less or No Color at all. So the ColorGrade Quality becomes higher compare to those who gets visible color.

 

 

Clarity

Lab Grown Diamonds do contain little imperfections.

The Lesser the Imperfections in Lab Grown Diamonds the Higher will be the Clarity-Grade.

 

 

Carat Weight

Carat is being a well known Term in general.

It is a Specific Weight Measure of the Diamond (& so does with Lab Grown Diamond).

 

 

Around the Globe, the above 5 Criteria are widely accepted in order to justify the Qualitative Standards of Lab Grown Diamonds.

 

Lab Grown Diamonds (made through HPHT or CVD) can be cut into Gems. Afterwards other Colors as below are being produced.

  • Clear White
  • Yellow
  • Brown
  • Blue
  • Green
  • Orange etc

Lab Grown CUT Proportions

The Proportions of Lab Grown Diamonds can be categorized after determining the Relationship between the Size, the Shape & the Angle among Each Facets. There can be a number of Combinations. These combinations are summarizing the Interactions between the Light & the Lab Grown Diamonds.

 

Light when hits the Lab Grown Diamond about 20% of the Light get reflected off the Surface on an instant. The Remaining 80% however gets it entry into the Lab Grown Diamond. Out of that, a Portion of Light will get escaped through the Bottom of the Lab Grown Diamond. It is not detectable easily through the Observer.

 

Each of the Facets will be Placed & Angled appropriately in a Well Proportioned Lab Grown Diamond. Thereby, the more percentage of light will be reflected back out of top of the Lab Grown Diamond and from there to the eye of the observer.

The light that reflected is called as a Brilliance of the Lab Grown Diamond.

 

3 most usual Light Patterns are as below.

 

 

Light when hits any facet of the Lab Grown Diamond, it will either Reflect or Refract.

  • Reflected Light means Bounced Back Light.
  • Refracted Light means light gets bent while passing through the facet.

 

The Importance of Cut is explained by the Angle by which the light hits the Facet as a whole.

 

  1. Shallow

In too Shallow Cut of the Lab Grown Diamond, Light hits the Pavilion Facet at relatively low Angle. Then it gets refracted (it simply passes through the facet) that in turn gets escaped through the bottom of the Diamond.

  1. Ideal

In Properly Cut Lab Grown Diamond, Light hits each Pavilion facet at specific Angle through which Mostly the Light gets reflected back to the Top (Crown). After when it gets passed through those Top facets at relatively low angle, the Light gets refracted from there.

However, Refraction is so good that when that bent light is watched by the Observer’s eye it appears to be the Amazing Brilliance of the Lab Grown Diamond.

  1. Deep

In too Deep Cut of Lab Grown Diamond, the Light hits the 1st Pavilion Facet at some specific Angle in order to be reflected to the 2nd Pavilion. However, light hits at relatively low angle to the 2nd Pavilion which causes the light to have refracted & afterwards it gets escaped through the Bottom of the Lab Grown Diamond.

 

 

 

Diamond Depth %

 

From the Side View of the Diamond; the distance between the Table & the Culet is referred to the Depth. Normally the Depth of the Lab Grown Diamond is measured in Millimetres.

 

We (at Kakadiya) follow below Measurement in order.

  1. Length
  2. Width
  3. Depth

Thus, Depth comes 3rd under our Measurement of Lab Grown Diamonds.

 

 

After Dividing Depth by the Width of the Lab Grown Diamond, Depth% can be derived.

 

  • As an Example

Depth of the Lab Grown Diamond is 3mm

Width of the Lab Grown Diamond is 4.5mm

Thereby,

The Depth% will be 3/4.5 = 66.7

 

 

Diamond Table%

After Dividing Width of the Table facet by the of the Lab Grown Diamond, the Table% can be derived.

 

  • As an Example

Table Facet is 3 mm

The Width of the Lab Grown Diamond is 4.5 mm

The Table% will be 3/4.5 = 66.7

 

 

How to Decide Cut Grades?

We (at Kakadiya) are following the Cut Grades of Lab Grown Diamonds described by GIA. We also have our own Cut Grade Standards as per the Proportion formula like GIA. Our Cut Grade is based on number of different factors. If comparing Our Cut Grade & GIA Cut Grade, Our Cut Grade will either be Equal or 90% equivalent to the GIA Cut Grade. In this way, there won’t be difference between the Cut Grades of Ours & GIA.

 

We follow below Cut Grade scales.

 

  • Excellent

Nearly all light that hits Lab Grown Diamond get reflected, creates super awesome Fire, Brilliance & Exceptional Sparkle & Life.

 

  • Very Good

Most of the Light hits Lab Grown Diamond gets reflected & produces Greater Fire & Brilliance.

It seems same as Excellent Cut if seen under the Normal Lighting Conditions.

It tags with relatively lower price however.

 

  • Good

Majority of Light hits Lab Grown Diamond get Reflected & renders the Above Average Appearance.

Comparatively it produces the Excellent Value.

 

  • Fair

Much of Light hits the Lab Grown Diamond gets escaped from the Side or Bottom & it lower down the Fire & Brilliance.

In Less than .75 Carats Lab Grown Diamonds, the relative difference in Sparkle is not easy to detect.

 

  • Poor

Most of Light hits the Lab Grown Diamond gets escaped from the Side or Bottom.

Generally the appearance itself of the Lab Grown Diamond seems to be Dull or Lifeless to the Necked Eye.

Thereby, we just don’t offer any sort of Poor Cut Lab Grown Diamond.

 

 

Diamond Proportion Diagram by GIA

 

 

 

 

 

 

 

 

 

 

Each & Every Lab Grown Diamond at Kakadiya has its own individual grading & Certification. In which mostly Proportion Diagram is being included as well. Basically the Graphic Representation of the Actual Proportions of the Lab Grown Diamond is what the Proportion Diagram is in real.

 

The Proportion Diagram of Lab Grown Diamond will show below.

Clarity Details

 

  • Small Imperfections are bound to be found inside the Lab Grown Diamonds.
  • Clarity Measure gives us the Number & the Size of those Imperfections as a whole.
  •  

Most of these Imperfections are Microscopic. Thereby, the Elegance of Lab Grown Diamond isn’t affected in anyways. Natural Microscopic Characteristics are generally trapped within or on the Diamond while it was forming. Clarity Measure in this way helps determine how much Clean or clear the Diamonds are with respect to those Natural Microscopic Characteristics. 

 

 

About Inclusions

Characteristics on the Inside of the Diamonds are Inclusions. Inclusions can be any of the below.

  • Crystals of other Material
  • Structural Imperfections Such as

o   Tiny Cracks

o   Feathers

o   Whitish or Cloudy Appearance

 

Clarity gets affected by Inclusions value of below.

  • Quantity
  • Size
  • Color
  • Location
  • Orientation
  • Visibility

The Highly Valued Lab Grown Diamond gets for Less or No Inclusions at all. They are considered to be rarest of all. Characteristics on the Surface of the Gem are Blemishes.

 

 

Inspection

Maximum of 10X Magnification is used by Gemmologists in order to inspect the Lag Grown Diamonds for Clarity Grade. Diamonds are viewed from the Face up in the process by the Gemmologists.

 

In case of no inclusion gets visible while viewing from the top, the Clarity Grade is left undefined by them. They use Microscopes & Loupes for the same process. Loupes are small Handheld Magnifying Lenses. These instruments are used in order to have determined below Inclusion properties.

  • Size
  • Type
  • Positions

 

The Expert Graders only prefer the 10X Magnification in order to judge the Clarity Grade Characteristics. They map the Locations on “Diamond Plots” while processing. These “Diamond Plots” basically are the Small Maps for each Individual Diamond. They use Diamond Plots to identify the each Individual Stone.

 

Each & Every Lab Grown Diamond gets for the Unique Internal Pattern. Thereby, the Diamond Plots become the “FingerPrint” as the Individual Identity for the Lab Grown Diamond as a whole.

 

 

Clarity Grades classified in below are applied by the Expert Graders.

 

 

FL, IF

Flawless, Internally Flawless: No internal or external imperfections. Internally Flawless: No internal imperfections. Very rare.

VVS1,
VVS2

Very, Very Slightly Included: Very difficult to see imperfections under 10x magnification. An excellent quality diamond.

VS1,
VS2

Very Slightly Included: Imperfections are not typically visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades.

SI1,
SI2

Slightly Included: Imperfections are visible under 10x magnification, and may be visible with the unaided eye. A good diamond value.

I1,I2, I3

Inclusions are obvious under 10x magnification which may affect transparency and brilliance

 

 

Carat Weight

 

We won’t be able to measure the size of the Diamond by itself atleast not accurately. For that, a widely known Weight Measure of Diamond is used. That is known as Carat. The Size of the Lab Grown Diamonds is derived after viewing it from the Top just like how they are appeared to us when they are placed inside a ring.

 

2 Criteria are co-relatively taken into consideration while judging for the Carat Weight of the Lab Grown Diamonds.

  1. Distance in Millimetres across the Top of the Lab Grown Diamond
  2. The Cut Grade of the Lab Grown Diamond

 

 

Carat

Normally the Lab Grown Diamonds are measured in Carat. It is equivalent to 0.2g (or say 200mg). The Value of the Lab Grown Diamonds gets exponentially higher with respect to increase in the Carat Weight.

 

The Size of the Lab Grown Diamond is affected by the Weight of the Lab Grown Diamond. However the Average Size for its Carat Weight can be optimized by some techniques. The Diamond Cutter sometimes can optimize the Proportions from the Rough Lab Grown Diamond. After Finishing, Polishing & Cutting of Lab Grown Diamond is done, the Measures of the Lab Grown Diamond will be higher than the Average Size for its Carat Weight.

 

In anyways, it is possible to retain as much as Carat Weight in the Polished Diamond. Basically it is an outcome of the achieved yield from the Rough Lab Grown Diamond. The process however makes the Polished Lab Grown Diamond to have gained the Excessive Depth because of the alterations made into proportions. (These proportions carry inferior quality mostly) Thereby, they are not optimized for the Interactions with Light.

 

Diamonds can also make appear larger by some techniques. The Look of Lab Grown Diamonds can be changed. Diamond that sets High within a setting can be appeared as larger comparatively in a nutshell.

 

 

History of Carat Weight

The “Carat” word basically is derived from the Greek Word “Keration”. It means “Carob Seed” which in turn means “Small Horn”. Earlier it was being used just as the Counter Weight that measures for the Weight of the Precious Goods (like Gold or Gems). It is because Gold or Gems contain consistently & comparatively lesser weight.

 

It is also referred to as “Metric Carat”. The term was 1st used in the year of 1907 at the Fourth General Conference on Weights & Measures.

 

Diamond Size Chart

In the below Diagram, the Approximate Size of the Diamond is displayed. 

 

One of the Unit of Mass is Carat. It is equivalent to 200mg (0.2g or 0.007055oz). Mostly it is used in order to measure the Gemstones & Pearls. It is also known as “Metric Carat” Sometimes. (This “Metric Carat” term was adopted at the Fourth General Conference on Weight & Measures in 1907) After that it was used in most of the countries around the globe.

 

 

The Carat is generally divisible into 100 Points of 2 Milligrams each. However, there were also other Subdivisions & slightly different Mass Values that were used in various locations around the globe long time ago.

 

 

Color Details

 

Lab Grown Diamond Grading Scale For White Color

 

The Whiteness of Lab Grown Diamond plays an important role in order to decide for the Grading Scale as a whole.

  • M is the Lowest Possible Color Grade
  • H is the Highest Possible Color Grade

We (at Kakadiya) get you the range of Lab Grown Diamonds starting from the M Color Grade to the Higher up to H Color Grade.

 

 

The Color is much more of Apparent in Diamond. It normally appears as a Pale Yellow. Color Grade however is the thing how less the Color is inside the Lab Grown Diamond. Color is the 2nd Most Significant Characteristics for the process of Selection. The 1st is Cut Characteristics of the Lab Grown Diamond. Human Eye detects for the Sparkle 1st so.

 

We (at Kakadiya) get you the Nicest Color Grade Range (from G-M) of Lab Grown Diamonds.

 

The Color Grade J of the Lab Grown Diamond is the Better, Colorless or Near Colorless. However, it is difficult for the unaided eye to detect it.

 

 

Z-N

Noticeable color.

M-K

Noticeable color.

J-I

Near-colorless. An exceptional value with slightly detectable warmth or tone.

H-G

Near-colorless. Color difficult to detect unless compared side-by-side againstthe Lab Grown Diamonds of better grades. An excellent value.

F-E

  1. Minute traces of color can be detected by an expert gemologist. A rare diamond.

D

Absolutely colorless. Extremely rare. The highest color grade.

 

 

Kakadiya Lab Grown Diamonds Fancy Color Grading Scale

 

Fancy Color Lab Grown Diamonds gets for any of the below Color Properties.

  • Color Other than Light Yellow or Brown
  • More Intense Yellow or Brown than the “Z” Color Rating

 

Only 1 out of 10000 Lab Grown Diamonds can get for the Natural Color. In this way, this type of Lab Grown Diamond is Rarest of all.

 

The Value of Lab Grown Diamond is reduced or enhanced based on the below Color Properties.

  • Coloration
  • Intensity
  • Hue

 

 

The Colors of the Naturally Occurred Diamonds are as below.

  • Gray
  • White
  • Blue
  • Yellow
  • Orange
  • Red
  • Green
  • Olive
  • Pink
  • Purple
  • Brown
  • Black

 

Red Color is the Rarest in the Fancy Colored Lab Grown Diamonds.

 

Color of the Lab Grown Diamond is determined by its Natural Body Color. It is no way the Reflection of the Spectral Colors which gets flashed while Lab Grown Diamond is made moving.

 

A Slight of Yellow or Brown or Gray will be found inside the Lab Grown Diamond mostly. Those colors are the result of Present Nitrogen Elements inside the Lab Grown Diamond. The Lesser the Color in the Lab Grown Diamond the higher will be the Fire, the Rarity & the Value consequently. Less Colored Lab Grown Diamond allows more Lights to get passed through which releases the higher Fire & Amazing Brilliance as a whole. Diamond is just as the Prism that divides the Light into Spectrum.

 

If Cut is the 1st Important Characteristic then Color Preference comes in 2nd while doing selection process of the Lab Grown Diamond.

 

 

Kakadiya Group Fancy Color Lab Grown Diamonds

 

We (at Kakadiya) get you the below Color Ranges in terms of Fancy Colored Lab Grown Diamonds.

  • White
  • Blue
  • Brown
  • Yellow
  • Blood Red
  • Olive Green

 

 

Generally people tend towards White Colored Lab Grown Diamonds & thus it is more popular among all. White Colored (or Colorless Sometimes) Lab Grown Diamond are the produced with Pure Carbon. Other Colored Lab Grown Diamond however, gets some sort of impurities as below.

  • Blue Color has Boron Impurities
  • Yellow Color has Nitrogen Impurities

o   More Nitrogen implies More Yellow Colored Lab Grown Diamond

o   Too Much (or Excessive) Nitrogen implies Yellowish Brown Colored Lab Grown Diamond

 

We trade in Bulk Quantity thereby we offer you White Colored Lab Grown Diamonds with the Price Comparatively lower than the Market.

 

 

Irradiation

Irradiation is the Process of Shooting Neutrons or Electrons into the Lab Grown Diamond in order to Change the Crystal Lattice of the Lab Grown Diamond. This Process is Pretty Much Safe indeed.

 

As a result, New Colored Centres are being generated inside. The Produced Lab Grown Diamonds are generally Annealed or Heated. Thereby, further Appropriated Coloration can be achieved.

 

Annealing Process is helpful in order to correct few of the Alternations from Irradiation Process. As an outcome New Colors are created.

 

There won’t be Radiation in an Irradiated Lab Grown Diamond. So it is surely safe to have worn.

 

The Yellow Lab Grown Diamonds are processed by irradiation and as a result below colors are being created.

  • Pink
  • Purple
  • Red
  • Green

 

The Post Growth Treatment Process

It is most successful process with relatively smaller & lower Saturation Yellow Lab Grown Diamonds. The Higher the level of Saturation appears in the Lab Grown Diamonds the Darker the Color Tone will be in the output.

 

Example

Sometimes Fancy Intense Yellow are processed in order to get Normal Pink Color.

But instead it results as the Fancy Vivid or Deep Pink or Purple Color.

 

 

The Weight

It does have its effect in the Resulting Color. If the Diamond is thicker it is unlikely to have its Centre fully treated. Stones with ½ Carat are being Fully Treated. The Lighter the Tone & the Saturation the Easier it will be to have it fully treated.

 

Sometimes 1 Carat Yellow which supposed to have converted into Pink may turns into Peachy Color instead. It happens because might possibly some yellow Color is still there on the Centre adding to the Surrounding Pink Colors.

 

We have Successfully Irradiated below.

  • 1 Carat Green Lab Grown Diamonds
  • ½ Carat Vivid or Lighter Pink Lab Grown Diamonds

 

 

Stability

The Generated Colors are pretty much permanent. Thereby, the stability is higher and so can be used in Daily Wear.

 

However, we recommend a proper care while servicing a Color Treated Diamond. It is because they are being exposed to as high temperature as greater than 800 degrees sometimes. (Like the Torch of the Jeweller)

 

Sometimes, the Color gets unstable due to these high temperatures.

Because of this, Majority of Jewellers is doing “Cold Set” the Diamond without applying heat. They have to do it Safely & Securely.

 

The Below Lab Grown Colors are Stable.

  • Blue
  • Yellow
  • White

The above colors are pretty much permanent under all the conditions. Even while being set into the Jewellery with a torch.
