Black diamond stones

Posted By ~ 6th September 2010

If you think that all the diamonds are transparent in color then you’re in for a surprise. There are many diamonds which have certain colors. They are caller fancy colored diamonds and they are much rarer than transparent ones, hence they are also usually more expensive. Some of the most common diamond colors are yellow, blue and red. However there also are black diamonds. These are some of the rarest of them all. One of such diamonds is called the carbonaro and they are usually found in Brazil river basins. The carbonaro is not really good for diamond rings and other jewelries because it has a rough and porous surface which is very difficult to cut and make shine, however they are very suitable for industrial uses such as for drill heads. Because black diamonds are so rare, scientists are not yet sure how exactly they form. Some even say that they might be of alien origins.
