About this 1.23ct natural heart diamond

This 1.23ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6421591328. Listed at 13 retailers as of November 5, 2026, with prices from ₹3,66,664 to ₹8,02,265, a ₹4,35,601 spread on the same certified stone. NZ Jewellers lists it at ₹8,02,265. 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.
