If you are looking for a natural batch of sapphires, then we recommend this product. It contains round, yellow sapphires with some blue spots that are 3.30–3.40 mm in size and have a total weight of 0.65 carats. The sapphires have good clarity with faintly visible inclusions; they have been heat treated to improve their appearance. These stones come from Thailand and have been handcrafted; they have an irregular, round shape.

All corundum gemstones are known as sapphires, with the only exception of 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.
