What is the quality of the Diamond Hybrid?

The Diamond Hybrid® is guaranteed to come D to F in color, VVS1 to VS2 in clarity and rate a 1 to 2 on the AGS cutting scale or otherwise described as an “excellent” to “very good” cut. Only 1 in 1,000 earth mined diamonds will ever achieve the same cut grade as every Diamond Hybrid®. The index of refraction of an earth-mined diamond is 2.42 and the fire light dispersion is 0.044. Because the Diamond Hybrid® has an outer layer of infused diamond, its index of refraction of 2.24 and Fire/light dispersion of 0.041 is nearly identical to that of a natural diamond. This gives our Hybrid stone optical properties closer to an earth mined diamond than any other simulant being produced today.

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 Hybrid® 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 D to F on average.


Clarity: Clarity describes the clearness or purity of a diamond.  Clarity is determined by the number, size, nature and location of the internal (inclusions) and external (blemishes) imperfections of a stone. An earth-mined diamond nearly always has a birthmark as does the 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.

Cut: We spend a lot of time and effort on our cut - it must be perfect. The 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 it does 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,

Hardness and Durability: This outer layer of created diamond once integrated with the crystal core gives the Diamond Hybrid® an overall hardness of 9.1. The outer layer hardness of MiaDonna's lab created diamond is approximately 9.6 on the Mohs scale of mineral hardness with only a natural diamond measuring a 10. 

The Diamond Hybrid® is moderately harder than a Ruby or Sapphire, considerably harder than an Emerald and twice as hard as a CZ. However, it is not as hard as an earth-mined diamond, so we suggest it is treated like a ruby or sapphire. 

The CZ being offered by our competitor's, regardless of their claims, has a hardness of 8.5. The Mohs scale is ordinal, meaning the actual hardness increases exponentially. In the end, the Diamond Hybrid® when compared to CZ is nearly two times harder and more durable than a CZ.
