About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1379698927. Listed at 15 retailers as of November 5, 2026, with prices from ₹49,214 to ₹1,67,459, a ₹1,18,245 spread on the same certified stone. NZ Jewellers lists it at ₹1,67,459. 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.
