How does carat weight influence price?

• A. Price generally decreases with carat weight
• B. Price generally increases with carat weight; larger stones have higher price per carat due to rarity
• C. Price is unaffected by carat weight
• D. Price depends only on color

Answer: (B)

Carat weight has a direct and nonlinear impact on price. In diamonds, price per carat typically increases with weight because larger stones are rarer and in greater demand. That rarity premium means the total price tends to rise as carat weight increases, and the jump from one weight category to the next can be steep. While color, clarity, and cut also affect value, weight cannot be ignored when pricing. Statements that price decreases with weight, or that weight doesn’t affect price, miss how rarity and market demand drive the value of a diamond.
