About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1279100240. Listed at 6 retailers as of November 5, 2026, with prices from ₹4,69,694 to ₹5,78,854, a ₹1,09,160 spread on the same certified stone. 77 Diamonds lists it at ₹5,78,854. 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.
