History of synthetic diamonds

The synthetic diamonds have the similar appearance but different features comparing with the genuine diamonds. The synthetic diamonds is also different from the man-made diamonds which own the same characters with real diamonds. This page will guide you to know more about the history of synthetic diamonds.
In history, the cut glass might be the earliest material, which was used to generate a diamond. This material is easily to be cut and polished, and the cost is very low. However, this cut glass was been replaced by cubic zirconia. Since 1976, the synthetic diamonds have mainly been simulated by the use of cubic zirconium which is low-cost and durable. In addition, the hardness ratio of the cubic zirconium is nearly 9 and the hardness rating of a mined diamond is 10. Light handling feature of the synthetic diamonds which are made of cubic zirconium is similar to a genuine diamonds, and the difference can only be observed by trained eyes. Moissanite is another material which can be used to generate the synthetic diamonds and its hardness radio is 9.25 slightly lower than the real diamonds. Furthermore, this kind of materials own the whole properties of real diamonds other than the hardness ratio. It demands the professional equipment to confirm whether the gemstone are a diamond or only moissanite.
In fact, the synthetic diamonds have a long history, and this page is only tip of the iceberg. However, this will also tell you how the synthetic diamonds are made. And next time when you choose a synthetic diamond, you will understand the materials better.
