A stone's origin can dramatically influence its value:
- Burma (ruby, spinel) → legendary
- Mogok → top quality
- Kashmir (sapphire) → historic prestige source
- Ceylon (sapphire) → bright, coveted hues
- Vietnam (cobalt spinel) → ultra-rare colors
- Tanzania (Mahenge, vivid pink) → new market icons
Rarity arises from:
- depleted mines
- political instability
- low annual production
- geological uniqueness
A "Burma vivid red spinel" is not just a gemstone –
it is a piece of geological history.
