About this 3.21ct natural heart diamond

This 3.21ct natural heart sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 250000169667. Listed at 4 retailers as of November 1, 2026, with prices from $13,881 to $19,347, a $5,466 spread on the same certified stone. NZ Jewellers lists it at $19,347. 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.
