Instruments & Books

SSEF in its mission to carry out research on diamonds, gemstones and pearls also seeks to develop instruments that can serve the trade. This includes ASDI for small diamonds, the diamond spotter, PearlScan for pearls and the mobile UV-Vis spectrophotometer amongst others. Price lists for: Instruments and Books.

SSEF Diamond Spotter

The SSEF diamond spotter was initially developed as a reaction to the threat of HPHT treated diamonds (ie. GE POL™, Monarch™, Bellataire™) on the market. Since its introduction in 2000, hundreds of SSEF diamond spotters have been sold to members of the trade all over the world. We have received much positive feedback about this simple and rapid way of testing diamonds, confirming the importance that this method now has for the trade.

Please note that the SSEF diamond spotter™ has to be used in combination with the SSEF diamond illuminator™, a powerful shortwave ultraviolet light source (SWUV).

The SSEF diamond spotter allows for an easy separation into two groups of diamonds:

Group A: type IaA, IaAB and Ib. Such colourless diamonds have not been decolorised by a HPHT treatment.

Group B: type IIa, IIb and rare IaB. Such diamonds may have been treated by a HPHT treatment.

SSEF Blue Diamond Tester

  • The application of this electrical conductivity tester allows an easy separation of boron containing diamonds and diamonds with no semi conductive capacity
  • Type IIb diamonds contain traces of boron, and are semiconductors
  • The SSEF Blue Diamond Tester™ does not indicate whether HPHT treatment has been performed on a blue diamond
