Diamond Shape Price Comparison 2026

Shape is the second biggest driver of price after carat weight. Some shapes cost more because they waste more rough diamond during cutting. Here are how prices compare for a 1 carat lab grown diamond across popular shapes:

Shape	Relative Price (vs Round)	Best For	2026 Trend
Round Brilliant	Highest (+0%)	Traditional rings, max sparkle	Always classic
Oval Cut	5–10% less than round	Looks larger, elegant fingers	⬆ Most trending in India 2026
Emerald Cut	8–12% less than round	Minimalist, sophisticated look	⬆ Rising fast
Cushion Cut	5–8% less than round	Vintage aesthetic, soft edges	Stable demand
Princess Cut	5–8% less than round	Modern, square shape, lots of sparkle	Popular with Gen Z
Pear / Marquise	3–6% less than round	Statement pieces, elongated fingers	Niche but growing

In India, oval and emerald cuts are the fastest-growing shapes in 2026 because they appear significantly larger than a round diamond of the same carat weight — giving buyers more visible diamond for their budget.
