Documentation for finished jewelry

A finished piece is more than its center stone. The Jewelry Report documents the article as a whole: the center stone graded as the mounting permits, every side stone screened, the metal identified and its stamp verified, and the piece photographed as received.

The report is written for the piece’s life after the sale: the language your customer’s insurer and appraiser expect, with every qualification stated on the face of the document.

The examination

What happens to a piece between intake and report.

  1. Intake & photography

    The article is logged under dual control, weighed, measured, and photographed from standard angles. The photograph prints on the report and its card.

  2. Stone mapping

    Every stone position is counted and recorded, center and sides, before any testing begins.

  3. Center stone examination

    Identity testing and spectral screening, then grading: color against master stones as viewing angles allow, clarity at the microscope, weight calculated from measurements and stated as calculated.

  4. Side stone screening

    Each side stone is tested in place to confirm diamond identity, with any inconsistency flagged by position.

  5. Metal & findings

    The alloy is identified, the stamp is verified against the test result, and clasps or closures are noted where relevant to the article.

  6. Report, card & registry

    The report is issued with the Jewelry Card Report, and the record enters the registry the same day.

Common questions
Why are mounted grades stated as ranges?
A mounting hides parts of the stone and limits viewing angles. An honest laboratory states what it could verify: a minimum grade range and a calculated weight, each labeled as such. An exact-sounding number on a mounted stone is a guess wearing a suit.
Is the report an appraisal?
No. The report is a statement of gemological findings, not a valuation. Insurers and appraisers use it as the factual basis for their own figures.
Which articles are accepted?
Rings, bracelets, studs and earrings, pendants, and tennis necklaces. Unusual articles are reviewed at intake; ask client services before shipping.
Can I get a loose-stone report instead?
Yes, if the stone is submitted before setting. Once mounted, grading is qualified as the mounting permits; many clients certify the center stone loose and document the finished piece afterward.
