This 0.51ct natural heart sits in the half to three-quarter carat band, graded H 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 5556256128. Listed at 2 retailers as of November 5, 2026, with prices from ₹34,469 to ₹43,146, a ₹8,677 spread on the same certified stone. 77 Diamonds lists it at ₹43,146. 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.
