Why do larger diamonds often command a price premium?

• A. They are rarer
• B. They are easier to cut
• C. They have more inclusions
• D. They fluoresce more strongly

Answer: (A)

Larger diamonds command a price premium mainly because of rarity. Natural diamonds of greater size are far less common than smaller ones, so the pool of stones that meet desirable color and clarity standards shrinks dramatically as carat weight increases. That scarcity means fewer buyers compete for the same large stones, driving prices up, and often in a nonlinear way that makes the premium larger than proportional to the extra carats. The size itself is a strong visual factor—people value the noticeable impact of a bigger stone—so the market is willing to pay more for that presence. Cutting ease, inclusions, and fluorescence don’t consistently explain a premium for size: larger stones aren’t necessarily easier to cut, inclusions and fluorescence vary independently of size and don’t reliably cause a price jump just from being bigger.
