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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558196256. Listed at 3 retailers as of November 5, 2026, with prices from ₹4,83,218 to ₹6,05,121, a ₹1,21,903 spread on the same certified stone. 77 Diamonds lists it at ₹6,05,121. 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.
