Coloured gemstones come in an incredible array of colours and varieties. Emeralds, rubies and sapphires are most well-known, but our testing services and research efforts go far beyond these three varieties. Our expertise in treatment detection and origin determination of coloured gemstones is based on decades of research, a large reference collection and continuously developing new techniques to analyse these treasures of nature.
WE TEST DIFFERENT TYPES OF COLOURED STONES :
– single or series of loose coloured gemstones
– gemstones mounted in jewellery
– coloured stone bead necklaces
