Kashmir Sapphire
Origin: Jammu & Kashmir, India
What Makes It Special
The Kashmir mine is dead. It essentially stopped producing in the 1930s. When I handle a Kashmir sapphire, I'm handling history—every stone on the market came from an estate or auction, never from new production. What you're paying for is the 'velvety' quality, a sleepy glow created by microscopic rutile inclusions that paradoxically reduce clarity slightly but create a color unmatched by anything else on earth. If it doesn't have an SSEF or Gübelin report, it's just a blue stone. When verified, it's the pinnacle of colored gemstones.
Required Documentation
A Kashmir sapphire without an SSEF or Gübelin report should be priced as unverified. The premium for verified Kashmir over unverified is 3–5x.

Dealer's Notes
Kashmir sapphires should carry an origin report from SSEF, Gübelin, or AGL — this is industry standard for significant colored stones, not an unusual request. A reputable dealer will always accommodate a purchase subject to lab certification. GIA is acceptable as a secondary certificate or for less expensive stones, but SSEF or Gübelin are the gold standard for Kashmir origin. A dealer unwilling to allow a subject-to cert on a significant Kashmir purchase is a genuine concern.
The mistake most collectors make is avoiding inclusions entirely. The 'velvety' quality of a true Kashmir comes from microscopic rutile inclusions. Paradoxically, the very thing that reduces clarity slightly is what creates that prized, sleepy glow you're paying for.
Pale Kashmir is still Kashmir. I've bought lighter-colored stones with solid origin documentation that still trade at 5-10x the price of an equivalent Ceylon. The origin is the asset.
My favorite buying opportunity? Estate sales where the seller has no idea what they're holding. I look for Victorian and Edwardian pieces; they frequently contain Kashmir sapphires that predate modern origin documentation.
I focus on the stone, not the story. The Kashmir mines essentially stopped producing in the 1930s. Every genuine Kashmir on the market came from an estate or an auction, never from 'new' production.
