Our lab-grown diamonds
Producing lab-growns:
Indistinguishable, even by experienced gemologist, lab-grown diamonds are created by replicating the natural diamond growing process.
First, a diamond seed is placed inside a sealed, oven-like chamber. Then the gases in a plasma cutter are ionized after which carbon-rich gas is ionized, and the pure carbon attaches to a diamond seed. The carbon crystalizes slowly, forming a crystalline structure.
Thanks to this cutting edge technology, we can proudly wear diamonds again.
Warranty:
Complimentary lifetime warranty on all orders.
