Carbide tipped engineer’s scribers |
||||
 |
Carbide tipped scribers are used by jewellers and gemologists as a quick and easy way to discern natural coloured diamonds from “treated colour” diamonds. | |||
 |
Diamonds that have had a surface colour coat applied to them are worth considerably less than natural coloured diamonds or irradiation and HPHT (high pressure high temperature) treated coloured diamonds. | |||
 |
Jewellers and gemologists can use a carbide tip scriber to scratch the pavilion and crown facets of a diamond. If they have been surface coloured, then the scriber will scratch away the surface coating.
As carbide is not as hard as diamond, the diamond itself is not scratched. |
|||
 |
This enables jewellers to quickly and easily tell if the diamond they are buying is surface colour coated or not and so allow them to more accurately determine its value. | |||
