This was because of the fact that it took many years for General Electrical to supply a manmade diamond that might measure up to the quality of a natural diamond and when they worked out ways to do it, they discovered that it cost more to provide a man-made diamond than it probably did to mine and cut natural diamonds.

Ultimately , a little company by the name of Gemesis Firm worked out a technique to produce man-made diamonds that were of the same quality as natural diamonds, at a less expensive cost. These diamonds sell for approximately third of the price of a natural diamond, but there is a deficit of them, and they are difficult to find.
