How are individual stone prices generally referred to?

Individual stone prices are generally referred to as unit prices. This term is widely used in the gemstone trade to indicate the cost of one individual piece, whether that be per carat, per stone, or per specific measurement. Unit pricing provides a clear, straightforward way to compare the cost of various stones, allowing buyers and sellers to easily assess the value of a gemstone based on its unique characteristics.

In contrast, other terms like premium prices or market prices typically encompass broader concepts. Premium pricing might refer to prices that are higher due to the rarity or quality of a stone but doesn’t specifically denote the price of an individual stone. Market prices indicate the general cost trends in the industry but can fluctuate widely and don’t always represent the price of a single unit. Value prices might imply a stone's worth based on subjective factors but do not detail the specific price per unit. Therefore, the term unit prices is the most accurate label for prices associated with individual gemstones.
