DIAMONDS
Composition
-
Diamond is made with 99.95% of a single element: carbon
-
Graphite shares the same unique feature with Diamond but their formation and crystal arrangement are very different. As a result although chemically the same, graphite is so soft it is use for writing, and diamond is the hardest of gems. Only a diamond can scratch another diamond
Colours
-
Diamonds come in many different colours. The largest number comes in the range of colorless to brown but the rarest are in fancy colours.
-
Most valuable hues are pink, blue and green. The strongest and more vivid colours commend higher prices.
