Synthetic is a blanket term that refers to all manmade materials used for the purpose of imitating and replacing the genuine natural product. A majority of the synthetics used in the gemstone trade are the synthetic Spinel’s and synthetic Corundum’s. Both of these are made in a wide variety of colours and are readily and inexpensively manufactured so are ideal for producing durable and well priced gemstones especially for costume or bling jewellery. There are a number of other materials used in synthetic production but for the sake of simplicity 90% is Spinel, Corundum orCubic Zirconia. |
