About the MiaDonna Diamond Simulant

• MiaDonna diamond Hybrid ranks; a. D to F in color
• VVS1 to VS1 in Clarity (There are natural feathers in the diamond layer – just like an earth mined diamond, however you cannot see them with the naked eye.)
• Ideal to Very Good in Cut
  

These are among the best grades you can get. Earth mined diamonds of this cut, color and clarity would cost $10,000.00 or more PER CARAT.

Color: Color describes the amount of color the diamond contains. This can range from colorless to yellow with slight tints of yellow, gray or brown. Colors can also range from intense yellow to brown, blue, green, pink and red. It is very rare and extremely expensive to find colorless earth mined diamonds. The MiaDonna Diamond perfectly mimics the diamond's crystal structure (face-centered-cubic) resulting in the virtually identical look of fine diamond. It grades F-G on average (the consensus of five gemologists) but new studies show our diamond hybrids are now becoming D to F on average.
 

GIA	COLOR – COMMERCIAL GRADING
D E F G	COLORLESS (WHITE) MIADONNA DIAMOND HYBRIDS
H I	COLORLESS/NEAR COLORLESS
J, K, L	NEAR COLORLESS
M	FAINT YELLOW
N, O, P, Q, R	VERY LIGHT YELLOW

Clarity: Clarity describes the clearness or purity of a diamond. This is determined by the number, size, nature, and location of the internal (inclusions) and external (blemishes) imperfections. An earth mined diamond nearly always has a birthmark and now, so does the MiaDonna Diamond Hybrid. Within the diamond layer we intentionally create ‘feathers’ which gives the hybrid stone a more natural appearance. These feathers cannot be seen with the naked eye.

The clarity scale is broken down into the following grades:

*MiaDonna Diamond Hybrids represented in light grey.

Symbol	Meaning	Definition
F	Flawless	Free from all inclusions or blemishes
* IF	Internally Flawless	No inclusions visible at 10x magnification.
* VVS1	Very Very Slightly Included #1	Inclusions that are extremely difficult to locate at 10x.
* VVS2	Very Very Slightly Included #2	Inclusions that are very difficult to locate at 10x.
* VS1	Very Slightly Included #1	Minor inclusions that are difficult to locate at 10x.
* VS2	Very Slightly Included #2	Minor inclusions that are somewhat difficult to locate at 10x.
SII	Slightly Included #1	Noticeable inclusions that are easy to locate at 10x.
SI2	Slightly Included #2	Noticeable inclusion that are very easy to locate at 10x.
II	Included #1	Obvious inclusions. Somewhat easy to locate with the unaided eye.
I2	Included #2	Obvious inclusions. Easy to locate with the unaided eye.
I3	Included #3	Obvious inclusions. Very easy to locate with the unaided eye.

Durability: Testing via the hammer smash test indicates that our MiaDonna Diamond Hybrid is the toughest, most durable diamond alternative product we have ever tested. When looking at the Diamond Hybrid using the Mohs hardness scale, it scores 9.6 to 9.8 on the outer diamond layer and 9.1 on the entire stone including the seed. (Natural diamonds score 10 for the hardest mineral.)

Cut: We spend a lot of time and effort on our cut- it has to be perfect. The MiaDonna Diamond Hybrid is hand-cut to precision and grades better in every aspect of the Gemological Institute of America (GIA) diamond grading scale than most diamonds.

This level of cutting perfection will only ever be achieved once in every 1000 earth mined diamonds. For example, it takes our cutters 8 times as long to cut a MiaDonna Diamond Hearts and Arrow cut (H&A) as to cut a typical round natural diamond. While color and clarity are big factors in the cost of a diamond, it is the 'cut' that breathes life, beauty and dazzling brilliance into a diamond. The three diamonds shown below are all SI2 Clarity and G-H Color, but there is a big difference in their appearance, due to the quality of cut.

SI2 Clarity, G-H Color, Fair Cut (A deep cut usually makes the diamond appear dark)	SI2 Clarity, G-H Color, Very Good Cut (A proper cut unleashes the fire and brilliance within a diamond)	SI2 Clarity, G-H Color, Fair Cut (A shallow cut usually makes the diamond appear opaque)
