GGTL Certificates
Insight

From now, all GGTL reports will be exclusively in English.

From September 2020, all GGTL Laboratories reports are exclusively in English. Bilingual documents (french or german) will be available upon request.

 

However, our formats remain the same:

  • Short Report.

The Short Report is an A4 size document. It is as brief as possible, with neither picture nor signature. The report contains the identification of the gemstone and its treatment but does not mention the geographical origin. It is optimal for low value good, such as common gemstones, gem materials and syntheses.

  • Report

The Report is an A4 size document. It is a complete description of the gemstone(s), with picture and signatures. The report contains the identification of the gemstone, its treatment, diagram (for diamond) and geographical origin upon request. This document is optimal for valuable loose gemstone, diamond, pearls, set of melee diamonds and jewellery.

  • Mini Report

The Mini Report is an A5 size document. It contains a short description of the gemstone, with picture and signatures. The report contains the identification of the gemstone and its treatment but does not mention the geographical origin. This document is optimal for a loose colourless diamond weighing less than 6 carats and a loose coloured gemstone weighing less than 10 carats.

  • Jewellery Report

The Jewellery Report contains several A4 pages. It contains a complete and detailed description of the gemstones set on the jewellery, with picture and signatures. The report contains the identification, treatment and the geographical origin upon request. This document is optimal for special adornments as the items are prominently displayed on a full-page photography.
