About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1226341518. Listed at 12 retailers as of November 2, 2026, with prices from ₹4,29,249 to ₹9,54,700, a ₹5,25,450 spread on the same certified stone. Belgium Diamonds lists it at ₹9,54,700. 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.
