About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded D 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 1357781607. Listed at 7 retailers as of November 1, 2026, with prices from ₹8,67,178 to ₹11,35,602, a ₹2,68,424 spread on the same certified stone. Jared lists it at ₹11,35,602. 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.
