It is the most beautiful, realistic, natural looking diamond simulant ever created and compliments the finest earth-mined diamonds superbly.

Results from MiaDonna run tests conclude that 4 out of 5 jewelers cannot tell the difference between our diamond simulant and an earth-mined diamond using their natural eye.



Created by placing a perfectly cut crystal core or substrate into a chamber of intense heat and pressure and infusing lab-created diamond crystals, or bonding them at a molecular level, into the outer layers of the crystal core. These lab created diamond crystals stack up on the core and realign with each other. The finished product is a diamond infused simulant that has a non precious crystal core and a solid outer layer of lab-created diamond that will never wear off or detach from the core.

Hardness and Durability

Our hybrid diamond has the same hardness as a precious gem, like a Sapphire or Ruby, and should be treated with the same care. Because of its infused outer diamond layer it is also nearly two times harder than an ordinary CZ and will not absorb oils from the everyday use of soaps, lotions and/or beauty products.

The outer layer consisting of lab-created diamond is non-porous just like a natural diamond, so the it will never cloud or discolor. Click here for care and cleaning instructions.

Diamond Grading and Analysis

MiaDonna uses the highly recognized Global Gemological Lab located in California, USA. The GGL grades for many companies you've already heard of like Fred Meyer Jewelers, Kay Jewelers and Jared's. We like the idea of providing our customers grading cards from a real company that has already established themselves as a leader in the diamond grading and appraisal industry in order to offer an independent, unbiased opinion and grading of our diamond simulant.

  1. The GGL will grade the cut, clarity, color and carat size of your center stone and any other accenting stones used in your setting. The grading card will also identify the precious metal used in creating your ring.
  2. The second piece verifies technology and states that MiaDonna's Simulated Diamond Hybrid is a diamond simulant with an infused outer layer of man-made diamond.

All hybrid stones purchased from MiaDonna will automatically come with an Identification Card from the Global Gem Lab giving a brief statement as to the technology used to create our diamond simulant. However, If you wish to have your finished piece sent to the lab for grading of the actual stones set in your ring simply add the Grading Card at checkout and we will ship your finished ring to the lab where every stone will be individually graded on its 4C's using the identical qualifiers used to grade earth mined diamonds.

Complimentary Identification Card

This is the identification Card from GGL with a brief description of the technology used when creating our hybrid diamonds.
