Delivering clarity, transparency and confidence for both jewellers and consumers — even on pieces set with multiple or very small lab-grown diamonds.
JTR Lab-Grown Jewellery Reports are expertly designed for pieces featuring multiple or small lab-grown diamonds. Our advanced methods ensure accurate documentation of diamond characteristics even when set in complex designs.
Lab-Grown Jewellery Reports are the preferred report type when there is more than one lab-grown diamond on a jewel, or because the diamonds are very small. Having a diamond attached to a jewel makes grading difficult — so at JTR we rely on technology and continuous research to solve these complex problems.
Confirms that the set diamonds are synthetic / laboratory-grown, using photoluminescence spectroscopy to read each stone’s chemical fingerprint.
Precise measurement of the total lab-grown diamond weight, with per-group carat validated on request.
Identification of the lab-grown diamond colour grade in line with international 4Cs standards.
Documentation of internal and external features according to international 4Cs standards.
Categorisation of diamonds based on size, colour, clarity and cut for detailed, resolvable analysis.
Detection of metals, purity and coatings with advanced XRF and Raman spectroscopy.
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.
Responds to light at a latent wavelength — measurable only spectrometrically, making duplication impossible.
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.
