The prices for red diamonds are almost beyond the reach of some: A single carat can cost between CHF 1 and 2 million, while heavier stones can cost up to CHF 10 million per carat. Investing in red diamonds means investing in a jewel that not only impresses with its beauty, but also with its exceptional performance. Due to their rarity and global demand, red diamonds are considered one of the most exclusive investments in the diamond sector.
