How Diamonds Are Made


How Diamonds Are Made

There are actually two kinds of diamonds, both of which may be natural - created in the earth as a result of geologic processes - or artificial, created under laboratory conditions. Furthermore, diamond may be of "gem quality," which is used in wholesale diamond jewelry, or "industrial quality," for use in cutting machinery.

In either case, the key is preternatural amounts of heat and pressure. When carbon is subjected to pressures of 45 - 60 millibars (45,000 - 60,000 times normal air pressure at sea level) and heat of at least 2300 degrees F (800 degrees hotter than the melting point of structural steel), its molecular structure changes from a flat, hexagonal pattern to a box-like one. It is this particular structure that gives diamond its hardness as well as the octagonal shape of the rough stones.

Cutting The Stone

The value of wholesale diamond jewelry is dependent on the cut, which is something that jewelry wholesalers look at closely. Until modern times, diamond cutting in preparation for the creation of wholesale diamond jewelry could be accomplished only with diamond, due to that substance's hardness. Not only that, but the process was uncertain and involved an extreme amount of nerve-wracking, painstaking precision.

Today however, diamond that is used in wholesale diamond jewelry is cut with lasers, using computer-aided design. Nonetheless, it is still a precision process that requires not only creative vision, but precision mathematical calculations as well. It is why the creation of wholesale diamond jewelry is as much science as it is art.

I never like to hear of problems with jewelry work or even of problems the jeweler might have from customers who have no clue as to what is going on. Good communications is the general solution for either. In your case, first appearances tell me the jeweler may have done less than the best. Then again, I am not there and only working in my thoughts with the words you have sent. Refreshing it is to have questions with enough information to actually work on a viable answer.

I am curious about the prong setting being bent. Unless the ring has a prong setting made originally as part of the ring, not soldered into the ring band but cast with the entire ring, and the ring had to be resized several sizes smaller, there should be no problem with the setting at all.
