Natural loose diamonds are rare, valuable and exquisite stones that have been formed deep within the earth over millions of years. These diamonds are unmounted, meaning they are not set in any jewellery, and are sold individually based on their carat weight, colour, cut and clarity. Natural loose diamonds come in a variety of shapes and sizes and are often used for bespoke jewellery pieces or investment purposes. They are highly sought after for their beauty and uniqueness, making them a popular choice for those looking for a one-of-a-kind piece.
