About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 250000108105. Listed at 13 retailers as of November 4, 2026, with prices from $1,495 to $3,952, a $2,457 spread on the same certified stone. NZ Jewellers lists it at $3,952. 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.
