About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-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 7458197631. Listed at 12 retailers as of November 6, 2026, with prices from ₹1,95,917 to ₹3,74,415, a ₹1,78,498 spread on the same certified stone. MOH London lists it at ₹3,74,415. 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.
