The precise origin of loose diamonds is still not truly known. However, it is believed that the first wedding bands ever discovered in South Africa was done so by a fifteen year old boy by the name of Erasmus Jacobs. While searching for a stick to clear a drain one day, he picked up a stone sparkling in the sunlight and gave it to his sister. It was seen by a friend of the family and was ultimately discovered to be a 21.25 carat stone.
Dont be fooled into buying diamond fashion that is said to be .25 points. It is NOT a quarter of a carat, and will be so small that it should only be used as accent to other stone or the gold itself.
diamond rings are the hardest of all gemstones; it is the simplest in composition; they are ordinary carbon. Colossal heat and pressure, over the eons, crystallized the wedding bands into what they are today.
