Most price lists quote prices on which basis?

• A. Per stone prices.
• B. Per carat prices.
• C. Per gram prices.
• D. Per package prices.

Answer: (B)

Diamons are valued primarily by weight, so price lists standardize on a price per carat. The carat is the unit that directly correlates with value, and knowing the price per carat along with the stone’s weight in carats lets you estimate price consistently across stones of different sizes. Pricing per stone would ignore weight differences, pricing per gram is used for metals or other materials, and pricing per package isn’t typical because each individual stone has its own weight and value.
