Why It Matters
A New Reference Language for Turquoise Quality
The Standard gives the trade a way to talk about rarity without reducing turquoise to price, provenance, or personal taste.
The Industry Problem
Turquoise has always had strong language for provenance, color preference, spiderweb patterns, collector reputation, and local expertise. What the industry has lacked is a common reference method for communicating the rarity of natural formation across stones.
What the Standard Adds
A Shared Point of Comparison
Authorized Master Stones give graders the same physical references for Color, Matrix, and Zat.
A Cleaner Conversation
A grade can discuss rarity while leaving beauty, price, provenance, and taste in their proper lanes.
A Verifiable Record
Official reports and registry records make the result easier to discuss, search, and verify.
Why Collectors and Dealers Should Care
Does this make provenance irrelevant?
No. Provenance remains important. The grade does not certify source or origin and does not replace provenance records.
Does this tell buyers what to like?
No. Color Master Stones represent rarity rather than preference. Personal taste and market demand still matter.
Does this make rare matrix easier to explain?
Yes. Matrix language becomes more specific: it refers to host rock or associated minerals in which turquoise is formed or embedded, in the finished stone.
Does this help with green or non-traditional preferences?
Yes. The color families are evaluated as defined ranges, so rarity can be discussed without treating one market preference as the whole story.
