Delivering clarity, transparency and confidence for jewelers and consumers. It applies even to pieces set with multiple or very small lab-grown diamonds.
JTR Lab-Grown Jewelry Reports are designed for pieces featuring multiple or small lab-grown diamonds. Our advanced methods document diamond characteristics accurately even in complex designs.
Lab-Grown Jewelry Reports are the preferred report type when a jewel carries more than one lab-grown diamond, or when the diamonds are very small. Setting a diamond into a jewel makes grading difficult. At JTR we solve these complex problems with technology and continuous research.
Confirms the set diamonds are synthetic / laboratory grown. Photoluminescence spectroscopy reads the chemical fingerprint of every stone.
Precise measurement of the total lab-grown diamond weight. Per-group carat is validated on request.
Identification of the lab-grown diamond color grade in line with international 4Cs standards.
Documentation of internal and external features according to international 4Cs standards.
Categorization of diamonds by size, color, clarity and cut. It enables detailed, resolvable analysis.
Detection of metals, purity and coatings with advanced XRF and Raman spectroscopy.
Every report is equipped with 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. It can be measured only spectrometrically, which makes duplication impossible.
Special markings visible only under ultraviolet light provide an additional layer of protection.
