Natural rubies are gemstones prized for their deep red colour and brilliance. These rubies have a burgundy-red colour, which is one of the most coveted shades of ruby. They are 1.90 mm in size and weigh 0.04 carats, making them suitable for mounting in fine jewellery. Clarity is excellent, with no inclusions visible to the naked eye, enhancing their value and beauty. These rubies have undergone heat treatment, a common and accepted method to enhance the color and clarity of gemstones. The heat treatment does not affect the durability or quality of the ruby, but only enhances its natural properties. They come from Mozambique, an African country renowned for its richness and diversity of gemstones. Rubies from Mozambique are renowned for their quality and purity, comparable to those from Myanmar, considered the best in the world.
