What is mélange in the diamond trade?
By Jared James · Last updated 21 May 2026
Definition
In the diamond trade, mélange refers to a mixed parcel of diamonds of varying sizes, generally used for parcels weighing more than one carat in total. The term is French for mixture, and it describes rough or polished diamonds sold together in an unsorted mix rather than graded and priced individually. Mélange parcels are common in the wholesale market and among cutters and dealers who buy in volume and then sort, grade and sell the stones individually. The term contrasts with melee, which describes very small diamonds under one carat.
Frequently asked questions
- What is the difference between mélange and melee diamonds?
- Melee refers to small diamonds weighing less than about 0.20 carats each, used as accent stones in pavé or channel settings. Mélange describes a mixed parcel of larger diamonds sold together in an unsorted batch, regardless of individual sizes.
- Why are diamonds sold as mélange?
- Selling diamonds in mixed parcels is efficient for the wholesale trade because it allows rough or mixed material to move quickly without the time and cost of individual grading. Buyers with the expertise to sort and value the parcel themselves can find good value in mélange purchases.
- Is mélange used in finished jewellery?
- The term itself refers to the rough trade rather than finished pieces. Once individual stones are sorted, graded and set, they would be described by their own characteristics rather than as mélange.
