Buying loose diamonds refers to purchasing unset diamonds that are not yet mounted in jewelry. Unlike buying pre-set diamonds in jewelry pieces, buying loose diamonds provides greater flexibility and customization options.
The benefits of buying loose diamonds include the ability to choose the exact diamond you want in terms of the 4Cs (carat, cut, clarity, and color), the ability to set the diamond in a custom-designed piece of jewelry, and potentially saving money compared to buying a pre-set diamond.
