About us

Gemometrics AB is based in Luleå which is the Northern Swedish high-tech hub where for instance Facebook has a prominent presence.

We provide professional users the means to efficiently determine whether a diamond is natural, synthetic (man-made) or treated (visually improved to increase the value). The tool is portable, durable and reliable – and is used to validate gemstones.

The founder of Gemometrics AB is gemmologist and geologist Torbjörn Lindwall, who for more than 20 years has worked with identifying and valuing Gems and jewellery for Companies, Authorities and Private clients all over the world. Torbjörn is also Research Advisor at Luleå University of Technology and Tutor at London based Gem-A (Gemmological Association of Great Britain).

The initial idea was developed by Torbjörn Lindwall due to the increasing insecurity in validating gemstones. The financial risk that buyers of gemstones is faced with is significant and affects the whole market behaviour. We offer the best alternative to give gems their true value and to assure the safe trade of Gems throughout the whole supply-chain from mine to end-client!
