Understand the practical differences between rough and cut gemstones, and how to decide which form suits your business.
6 min read
Rough, uncut stones are sold close to their mined state. Lapidaries and manufacturers who cut in-house favour rough because it gives them control over the final shape and yield, and it is typically priced lower per carat than finished goods of equivalent quality.
Cut and polished stones are ready for setting or resale. Jewellery manufacturers, retail jewellers and designers without cutting facilities generally prefer finished goods, since they remove the need for local lapidary work and reduce lead time to market.
The decision usually comes down to whether your business has cutting capability and how much control you need over final calibration. Many buyers order both: rough for signature pieces cut to exact specification, and finished parcels for faster-moving stock.
Frequently Asked
Generally yes, per carat, because the cutting, shaping and polishing work has not yet been done. However, yield loss during cutting means the effective cost of a finished stone depends on the rough's shape and clarity.
