About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two 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 1159967716. Listed at 26 retailers as of October 30, 2026, with prices from ₹4,55,285 to ₹10,12,547, a ₹5,57,262 spread on the same certified stone. NZ Jewellers lists it at ₹10,12,547. 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.
