How To Differentiate Between Precious Stones And Synthetic Stones?

Natural Stone is found in Nature, but may however have undergone treatment to improve its strength or appearance. The synthetic stone is entirely man-made in a laboratory, in order to reproduce the physical and chemical properties of a natural stone.


To know before buying your jewelry:


Most famous synthetic substitute is zirconium oxide, also known as Zirconia or CZ. The Chatham Diamond or Moissanite, a synthetic gem too, is the fruit of 65 years of research work by the American inventor of synthetic stones, Carrol Chatham.


Where the task becomes complicated is that we confuse Zirconia (synthetic) and Zircon, which is a Natural Stone. The Herkimer Diamond or Quartz Crystal is also used as an imitation stone.


– The Ruby


Ruby is often confused with another natural Stone: Pink Spinel or Red Spinel. A synthetic Ruby can be recognized from a natural Ruby with the naked eye. The synthetic Ruby will be flawless, while the natural Ruby will have tiny inclusions.


– The Sapphire


Its natural equivalents would be blue Zircon or Lapis lazuli. Sapphire is often treated to modify its appearance, but beware: treated Sapphire is not a synthetic Sapphire. It is once again the inclusions that will make it possible to differentiate a natural Sapphire from a Synthetic Sapphire.


– The Emerald


All that glitters is not gold, all green stones are not Emerald: beware of the green Beryls from Madagascar and those from Nigeria whose value is far from reaching that of the Emerald.


The Emerald can be recognized by its inclusions or 'garden'. Inclusions are generally perceived as a defect in gemology but here it is a characteristic specific to this fragile stone.


This is why you will have to be wary if you are presented with a green gem without inclusion, its origin will necessarily be doubtful.


What is a synthetic stone worth?


If a synthetic stone can look like two drops of water to a natural stone, or even exceed it in terms of beauty, its market value is very low. This is why we advise you to buy your stones from trusted jewelers like Yotreasure, who are subject to controls by specialized organizations.


Editor's note: Some jewelers are themselves taken in by wholesalers or resellers of precious stones, try when choosing circuits with as few intermediaries as possible to eliminate this type of risk.
