The device a jeweler uses to test for diamond authenticity works by measuring the heat transfer capacity of the stone. A diamond's thermal conductivity is much greater than that of any of the fakes...until recently when moissanite was developed. That synthetic diamond substitute has a coefficient very close to a diamond's, rendering the test unreliable. Even experts are challenged by the moissanite fakes. A reflectivity test had to be developed to guarantee detection. |
