About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7556434354. Listed at 19 retailers as of November 3, 2026, with prices from ₹3,16,604 to ₹9,81,370, a ₹6,64,766 spread on the same certified stone. NZ Jewellers lists it at ₹9,81,370. 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.
