Diamond, the Magic Crystal
Diamond is one of two allotropes of carbon- the 6 th element in periodic system. It’s known also as the hardest mineral in nature. Diamond’s “genetic” brother –graphite has absolutely opposite physical characteristics. Diamond is an excellent insulator while graphite is very good conductor of electricity. Optically diamond is perfectly transparent while graphite has no sign of transparency. Diamond is very hard; graphite is soft and can be used as a lubricant. The second after diamond hardest mineral is corundum (sapphire, ruby). Upon this, diamond is still 4 times harder than corundum. In jewelry business both diamond and corundum are in the list of most valuable gem stones. The superior optical characteristics and the hardness are the main values of diamond’s high demand in both industry and jewelry business.
Nothing can be more brilliant than diamond. The fascinating light-fire performance of diamond as a gem stone is possible because of the high optical density and cut proportions of the crystal. It’s done in a way that entering light after several inner reflections completely is coming out. While transparent diamond may have a different colors (all rainbow colors). Usually the price for regular 1 carat starts from $1,000.However the weight is not the only the critical point for price. There are some very famous and extremely expensive diamonds like The Blue Magic (12.02 carat) fancy vivid blue diamond. The Hope, the big rare blue diamond (45.52 carat) however the most expensive is the rare blue 6.04 carat (1carat=200mg) diamond with the breathtaking sparkle and price soled recently - US$7.98 million. It’s like a very condensed wealth – nearly $8 million in a tiny 1.2g crystal.
