About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5416106145. Listed at 18 retailers as of November 5, 2026, with prices from ₹5,48,775 to ₹12,34,766, a ₹6,85,992 spread on the same certified stone. NZ Jewellers lists it at ₹12,34,766. 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.
