History: What Is Synthetic Alexandrite? Due to the gemstone's rarity, many types of imitations and synthetics have been on the market since the early 1900s. Faux alexandrite from the 1920s was made out of the mineral corundum (sapphire and ruby) and then laced with chromium or vanadium to create the color-change effect. Creating synthetic alexandrite is an expensive process, so even lab-grown gemstones can be expensive.

Gold was generally used for a couple thousand years solely to create things such as jewelry and idols for worship. This was until around 1500 BC when the ancient empire of Egypt, which benefited greatly from its gold-bearing region, Nubia, made gold the first official medium of exchange for international trade

The history of the Marquise Cut dates back to the 18th Century. King Louis XV of France paid a jeweller, to create a completely unique shaped diamond that compared to the lips of his mistress. The cut has then been developed and modified, evolving it into the stunning cut known today.

Siffari Jewellery company was founded in 1941.
