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 15 retailers as of October 30, 2026, with prices from $3,350 to $8,107, a $4,757 spread on the same certified stone. NZ Jewellers lists it at $8,107. 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.
