About this 1.22ct natural heart diamond

This 1.22ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2537303263. Listed at 15 retailers as of November 5, 2026, with prices from $4,643 to $9,970, a $5,327 spread on the same certified stone. NZ Jewellers lists it at $9,970. 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.
