Diamonds were formed of carbon deposits more than seventy million years ago (some sources say even longer, billions even) under immense heat and pressure deep within the earth. The diamond bearing ore was brought to the surface through volcanic eruption. After the magma cooled, it solidified into “blue ground” or “kimberlite” where the precious rough is still found today.
The major sources of diamonds are Africa, USSR, and Austraila. Diamonds are graded by color, clarity, cut and carat weight.
Although diamonds are the hardest substance known to man it is not the toughest. Diamonds have a cleave angle and can chip or even break if worn while doing heavy work or if it receives a sharp blow. Even so, diamonds receive an “excellent” rating for every day wear. We suggest you remove all fine jewelry, diamonds included, when doing hard activities like moving furniture, gardening, cleaning, or playing football with the guys. Avoid placing your diamond jewelry where it might scratch another gemstone or get scratched by another diamond.
