In a handful of sites diamond-bearing product from these depths has long been carried up to your area by volcanic eruptions – and several of this materials was subsequently washed to the river beds the place diamonds have been very first located.

This test is damaging, like a diamond can scratch A different diamond, and isn't used currently. As an alternative, diamond identification relies on its remarkable thermal conductivity. Electronic thermal probes are widely Utilized in the gemological facilities to individual diamonds from their imitations.
