About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 400929150. Listed at 14 retailers as of November 4, 2026, with prices from $4,655 to $11,276, a $6,621 spread on the same certified stone. NZ Jewellers lists it at $11,276. 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.
