Deep Pink Sapphire

This natural sapphire is a 0.35-carat gemstone with a round shape and a size of 4.30 mm. Its colour is an elegant carmine pink that becomes intense under the influence of electric light, and its clarity is excellent with no visible inclusions. This sapphire comes from Sri Lanka and has undergone heat treatment. It is a valuable and delicate stone, suitable for various types of mounts and styles of jewellery.

All corundum gemstones are known as sapphire, with the only exception being the ruby-red variant, which is called ruby. However, the name sapphire is very common for blue gemstones, but this blue should not be understood as the colour of a clear sky but as all shades of blue up to very dark blue and even black. Sapphire is found in a wide range of colours and shades. Sapphire is a mineral that occurs as Al2O3 single crystals. The colour is determined by impurities such as Fe2+, Fe3+, Cr3+, Ti4+, or V4+. It has a hardness of 9 on the Mohs scale, after diamond. The rocks where sapphires have been found are called pegmatites, which, through erosion processes, have been transported and deposited in alluvium in river beds. The most important sapphire-producing countries are Sri Lanka (formerly Ceylon), India, and more recently, the USA, Australia and Nigeria.
