Coloured Diamond Crystal from Katanga

Ref: DiamColXtl

On the Moh's scale (1-10) of hardness, Diamond is 10. It is the hardest, natural, known substance to man. It is pure Carbon (black), which when compressed and fused at high temperature, deep inside the Earth, produces a brilliant white crystal (although it can be found in other colours). Diamond is the Birthstone for April.
Coloured Diamonds such as these cubic crystals from the Congo are generally rarer than white (colourless) diamonds and consequently more valuable. Blue Diamonds contain Boron and yellow diamonds owe their colour to Nitrogen. Most other colours such as brown are due to lattice defects. Several diamonds are illustrated to show variation in colour shape and size.

Each diamond is approx 0.08Ct in weight and 2mm wide. Supplied boxed and with a descriptive card including the above information.
