In addition to the hardness, the thermal conductivity (410 W/cm/K) and the (electrical) resistance of 1013 Ω-m of diamond are particularly high. This combination makes that diamonds can be used in electronic circuits to dissipate heat. Diamond behaves like silicon as a semiconductor and in liquid helium as a superconductor, as discovered in 2004.

Both characteristics can be seen on the rim. All these characteristics determine the purity of the stone, which is classified in different categories: LC, VVS1, VVS2, VS1, VS2, SI1, SI2, P1, P2, P3. The assessment is always done visually with a magnifying glass and under a lamp that emits a light equivalent to daylight. The magnifying glass has a magnification of 10 and is an achromate, free of spherical and chromatic aberrations. This means that the diamond can be seen through the lens of the magnifying glass in full sharpness and without colour deviations. |
