Jewellery Authenticity Report
Verification that the diamonds in your jewellery are natural
Delivering clarity, transparency and peace of mind for jewellers and consumers — when the only question is authenticity.
Delivering clarity, transparency and peace of mind for jewellers and consumers — when the only question is authenticity.
The JTR Jewellery Authenticity Report confirms whether the diamonds in a piece of jewellery are natural — a streamlined, practical option when authenticity is the only question.
Unlike a full Jewellery Report, it does not grade the 4Cs. Instead it documents the essential details of the jewel itself — metal, total weight, diamond count and stamp — alongside independent confirmation that the set diamonds are natural and genuine.
Confirms that the set diamonds are natural and genuine, using photoluminescence spectroscopy to read each stone’s chemical fingerprint.
Provides the total carat weight of the diamonds, as far as the mounting permits.
Records the total number of diamonds set in the jewellery for a complete inventory of the piece.
Documentation of the jewellery’s total weight, as provided or measured at the laboratory.
Detection of metals, purity and coatings with advanced XRF and Raman spectroscopy.
Verification of hallmarks or metal stamps present on the jewellery.
Our reports feature advanced anti-counterfeiting measures that ensure authenticity and peace of mind.
Prevents any alteration of report details. Hidden text can only be read under magnification.
Special markings visible only under ultraviolet light provide an additional layer of protection.
Connects directly to JTR servers for instant validation, confirming the report is authentic.
Add your company logo to reinforce your brand’s credibility and strengthen customer trust.
A JTR innovation that carries the report on the jewellery itself. The Tag pairs every essential detail from the grading record with two built-in security layers — so proof of authenticity travels with the piece.
Carat, colour, clarity, weight, metal, brand and product ID — the record's key data on a compact tag.
An iridescent hologram strip that responds to light and cannot be copied — the Tag's first anti-counterfeit layer.
