Diamonds. The hardest natural substance. Renowned for their beauty, durability and ‘fire’. Diamonds are colour graded from D (completely colourless) through to Z. (which is yellow/brown). Verifine uses conflict-free diamonds of G/H colour, which is a good quality colour grade still in the white spectrum, and Si1/Si2 clarity.
Black Diamonds. The hardest natural substance, black diamonds occur naturally. They are in fact not really black but they contain numerous dark inclusions which render the stone opaque and they appear black.
