About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded H 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 1557134574. Listed at 16 retailers as of November 2, 2026, with prices from ₹4,51,439 to ₹11,45,659, a ₹6,94,219 spread on the same certified stone. NZ Jewellers lists it at ₹11,45,659. 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.
