About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 260000071653. Listed at 5 retailers as of November 3, 2026, with prices from $2,791 to $5,957, a $3,166 spread on the same certified stone. NZ Jewellers lists it at $5,957. 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.
