About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551864390. Listed at 4 retailers as of October 29, 2026, with prices from ₹8,42,801 to ₹9,90,006, a ₹1,47,205 spread on the same certified stone. Blue Nile lists it at ₹9,90,006. 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.
