Every stone on visualgrit.com has a Stone Passport. It's a six-field structured record that appears on every product page, below the Add to Cart button. Together, the Passport is what turns a stone listing into a verifiable record rather than a marketing page.

The six fields
Stone ID is the unique identifier for the stone in our catalog. Weight is carat weight measured on a calibrated gem scale. Dimensions are length by width by depth in millimeters. Color is a plain-English description of what the stone actually looks like. Cut names the faceting style and, when we know it, the cutter and country. Treatment discloses what has been done to the stone: heat, no known treatment, or an honest acknowledgment that the record wasn't captured.

Why six fields and not more
The Passport is deliberately compact. Six fields capture the essential record a buyer needs without overwhelming the page or slowing intake. Any additional context (a story block for a hero stone, supply-chain disclosure for the Founders' Batch) lives in its own place on the site rather than cluttering the main record.

Why we don't claim what we can't verify.
A Passport is only useful if it's accurate. Filling the Treatment field with "untreated" on a stone we haven't tested would undermine the whole point of having a Passport. When we don't have the record, we say so. Template E on our product pages ("Treatment status not documented; assume may have been heat-treated per standard trade practice") is the honest default in that situation, and it applies to some of our Founders' Batch stones.
