LAB-GROWN DIAMONDS

After decades of research and development, our scientists can now precisely replicate the earth's natural growing process of crystallizing carbon into brilliant, conflict-free diamonds that are chemically, optically, and physically identical to earth-mined diamonds, yet cost 30 to 40 percent less (according to the Federal Trade Commission).

If you're looking for a stunning and eco-friendly choice, the exquisite brilliance of MiaDonna's lab-grown diamonds is beyond compare.

THE DIAMOND HYBRID

Another stunning option for those seeking conflict-free diamonds, the Diamond Hybrid is the most realistic-looking diamond simulant available, exclusively offered at $295.00 USD per carat. It is created by placing a perfectly cut crystal core into a chamber of intense heat and pressure and infusing Lab-Crown Diamond crystals (bonding them at the molecular level) into the outer layers of the crystal core. The result is a diamond-infused simulant with a non-precious crystal core and a non-porous solid outer layer of Lab-Grown Diamond that will never wear off or detach from the core.

The Diamond Hybrid is not pure carbon and, therefore, does not share the same properties of a mined or lab-grown diamond. However, the Diamond Hybrid has an outer carbon layer that is molecularly bonded to the non-precious substrate.

While we will always recommend our Lab-Grown Diamonds, the Diamond Hybrid is an excellent choice for more budget-conscious consumers, especially for jewelry that doesn't receive the wear and tear of regularly worn rings, like earrings and pendants. Our customers often use them as a future diamond placeholder or in their travel jewelry.
