This antique cocktail ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18ct gold and platinum.
The synthetic ruby ring is supplied with an IDGL diamond grading report card.
NOTE * In 1837 Gaudin made the first synthetic rubies by fusing potash alum at a high temperature with a little chromium as a pigment. Natural rubies and synthetic rubies look very similar on general observation. Synthetic rubies have a different internal colour banding and crystal structure which can only be identified under specific test conditions.
*NOTE: Contrary to what many people may think, the word "synthetic" does not mean fake when it comes to gemstones. In order for a material to be called "synthetic" it must have a natural counterpart. A synthetic ruby will have the same chemical composition as a natural ruby and therefore have an almost identical appearance to the naked eye.
The first ruby formed by melting two smaller rubies together was in 1817, and the first microscopic crystals created from alumina in a laboratory in 1837.
Common practice was to set and enhance fine quality antique jewellery with vibrant and colourful synthetic stones.
Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.
Date: Circa 1907
