Why Dark Green Spinel?

Green spinel is among the rarest colour varieties produced by Mogok's mines. The colour arises from iron and chromium interactions within the crystal structure, resulting in a deep, earthy green that is distinct from emerald or tourmaline. For collectors and specialist jewellers, a quality green Mogok spinel at this weight is genuinely difficult to source and represents a serious addition to any collection or bespoke commission.
