How to identify earth-mined diamonds?

Gemlogis utilizes different technology to identify and segregate gemstones. One of the most discussed subject are identifying earth-minded diamonds.

Scientifically, diamond of the Type IaA and IaAB absorbs short-wave ultraviolet light (SWUV) while Type IIa and IIb transmits SWUV light. Gemlogis have developed products such as the VISTA to help with the identifying process. The advantage of the VISTA is not only for testing loose diamonds but also applicable for mounted diamond (either opened-back or close back) such as a ring, pendant, or earring.

How reliable are Gemlogis Diamond Testers?

Tests performed by devices of Gemlogis are not equivalent to a gemmology lab test. Its function is designed to provide a quick indication and reference based on industry-approved technology involving heat conductivity and SWUV. The results are highly accurate providing all the criteria are met and that the devices are handled accordingly.

Certain products of Gemlogis, for example the VISTA, has been certified by ASSURE Tested Certification Mark through the ASSURE program as one of the best portable diamond testers. VISTA achieved the scoring results for ratio of synthetic diamond referred for further testing to the total number of synthetic diamonds of 100%. The scoring results for ratio of diamonds correctly classified as ‘diamond’ to the total number of diamond of 92.5%.
