About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551273825. Listed at 12 retailers as of November 5, 2026, with prices from ₹2,44,662 to ₹4,45,275, a ₹2,00,613 spread on the same certified stone. Helzberg Diamonds lists it at ₹4,45,275. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
