Loose diamonds are a type of diamond that hasn't been set into a piece of jewellery yet. They come in various shapes, sizes, and colours, and are often purchased by jewellers and diamond traders to create custom pieces or to resell. Loose diamonds are valued based on their cut, clarity, carat weight, and colour, and can be a great investment for those looking to add to their jewellery collection or for those interested in the diamond trade.
