About this piece

Ruby was the first gemstone manufactured at commercial scale — Verneuil flame-fusion synthesis has been running since 1902 — which is precisely why this site labels the distinction on every ruby it sells. This stone is lab-created corundum: the same chemistry, the same Mohs 9, grown in a furnace. It is offered as a laboratory-grown stone at a laboratory-grown price, not as a natural ruby.
