How Shape & Cut Impact Price
In India, the most popular diamond shape for engagement rings remains the round brilliant cut, known for its unmatched sparkle. However, shape plays a direct role in pricing:
- Round Cut: Most expensive due to high demand and greater rough diamond wastage during cutting.
- Oval, Cushion, and Emerald Cuts: Typically 10–20% less than round for the same quality.
- Fancy Shapes (Pear, Marquise, Heart): Can be up to 25% less expensive but offer unique style appeal.
For example, a high-quality 4 carat oval diamond may cost ₹5–10 lakh less than a round diamond of the same grade.

Price isn’t determined by size alone — the 4 Cs of diamonds (Cut, Color, Clarity, Carat) work together to influence value.
- Cut: Impacts sparkle; a GIA Excellent or Ideal cut delivers maximum brilliance.
- Color: In India, D to F color (colorless) is the most prized for high-end purchases.
- Clarity: Fewer inclusions mean higher prices; VS1 and above is ideal for 4 carats.
- Carat Weight: Price per carat jumps significantly beyond the 3 carat mark.
