Natural Tourmaline is a splendid semi-precious gemstone popularly known for its vast and diverse colour spectrum. Tourmaline's chemical composition includes a group of mineral species that are closely related, sharing the same crystal structure and the existence of a complex mixture of other elements such as calcium, manganese, and iron are mainly responsible for the colour of Tourmalines.

According to legends and folklore, Tourmaline was believed to have travelled over the rainbow and gathered its beautiful colours along with it. Different cultures have associated the properties of Tourmaline with various beliefs over time. Tourmalines were used in various ceremonies in ancient India to help people gain insight and distinguish between good and evil. It was believed by African civilization to have the ability to alleviate disillusionment and improve mental clarity.

The mineral hardness of tourmaline ranges from 7 to 7.5 on the Mohs scale, making it a good choice for jewellery, including rings for daily wear. Other types of gemstone jewellery, such as earrings, necklaces, and pendants, frequently feature tourmalines.

From pink to black, this gorgeous gemstone is available in a wide range of colours. While some common tourmalines such as schorl are fairly affordable, the rarer colours command a premium.

Since most coloured tourmalines are formed in a liquid-rich environment, these liquids frequently become trapped inside as inclusions during the crystal growth process. In most cases, tourmaline inclusions closely mimic thread-like cavities or long hollow tubes. Eye-visible inclusions are typical in red and pink Tourmalines but are often despised if the colour is intense and appealing. Regardless of the stone's vividness, tourmalines with prominent whitish inclusions are poorly received by dealers and consumers. On the other hand, green tourmalines are usually eye-clean. As a result, the presence of visible inclusions significantly reduces their value. The same is true for tourmalines of other colours: inclusions visible to the naked eye will lower the price significantly.
