About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5231715556. Listed at 2 retailers as of October 31, 2026, with prices from ₹38,550 to ₹51,800, a ₹13,250 spread on the same certified stone. 77 Diamonds lists it at ₹51,800. 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.
