The name of olivine comes from its olive-like fresh green lustre. As one of the oldest gems in nature, olivine was worn as jewellery as early as ancient Egypt. At that time, people thought that olivine could protect the wearer and expel dark fear, so they called it a "sun gem".
In recent years, olivine has attracted the attention of many jewellers and designers with its unique green and charming appearance, and has launched a large number of amazing works.
How to choose?
Colour - The main colour of olivine is olive green, but there are also yellow-green, yellow, brown, brown and other changes. The best-coloured olivine presents a rich and pure green, and the yellow or brown tone will reduce its value. However, pure green olivine is extremely rare, and most of the yellow-green olivines in circulation on the market at present.
Cutting - When purchasing, you can choose according to your personal preferences, but you should pay attention to whether the edges and corners of olivine are straight and whether the facet is regular. These factors will directly affect the brilliance and shining effect of olivine.
Weight - Peridot is brittle and extremely cracked, so the common gemstone-grade olivine is less than 3 carats, not many more than 3 carats, and more than 10 carats are rare. The largest existing gem-grade olivine in the world weighs 319 carats, and now exists in the National Natural History Museum in Washington, D.C. Hall. The unit price of olivine with a weight of more than 3 carats has increased exponentially. It is recommended to choose the size that suits you according to your personal needs.
Purity - The clarity of gem-grade olivine is generally high. When purchasing, pay attention to whether there are visible defects in the interior, such as black solid inclusions and gas-liquid inclusions. At the same time, be careful of cracks on the surface of gemstones. These factors will affect the value of olivine.
As a very cost-effective gemstone, olivine is not expensive, but it is very good-looking. Sisters who like olivine need to be carefully selected!
