About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 9 retailers as of October 28, 2026, with prices from ₹5,60,444 to ₹12,43,416, a ₹6,82,972 spread on the same certified stone. NZ Jewellers lists it at ₹12,43,416. 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.
