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.

2. Are natural diamonds valuable?

The price of diamonds fluctuates in the economy just like any other high-end good. Sometimes diamonds increase in value, while other times they decrease.

Melee diamonds are small—between 0.001 and 0.2 carats—so they are not very valuable. The average price of a 0.50 carat diamond is $1,500, and the largest melee diamonds are less than half of this weight.
