This sparkling 18k yellow gold pendant features a stunning 0.93 carat heart-shaped Gemesis diamond in the center, with 45 small gemesis diamonds to complete the look. Gemesis diamonds are 100% diamond, grown in a lab under extreme pressure from a natural diamond "seed". The process takes days, and the rough diamond is then cut, polished, and independently graded-exactly like a natural diamond. For the discerning customer who wants a real fancy colored diamond-but doesn't want to pay for the mining! Each Gemesis stone comes with a GIA or EGL Certificate.
