Small mobile gemstone laboratory KA41KRS

Professional assessment of gemstones with mobile devices

To ascertain the difference between synthetic, simulated, and real gems, away from the confines of the laboratory it is crucial for portable equipment to give the highest possible identification outcome. Appraisal in the field, at its very basic level, is carried out with a loupe, a flashlight, and a pair of tweezers. Not an ideal solution where identification is critical. Therefore, the use of portable high precision instruments will eliminate costly errors.

We recommend the KA41KRS, a gemmological test laboratory equipped with all standard instruments.
