Blackwell Tantalum Black Diamond Wedding Ring

You can choose either mined Diamonds or lab-grown diamonds.

Mined diamonds and lab-grown diamonds are the same - chemically, physically & optically. Only the origin is different! Man-made diamonds are simply created in a lab instead of the ground.

Typically, lab-grown diamonds cost 40-50% less than mined diamonds but this savings increases as the rarity of a diamond increases in carat, color, and clarity.
