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 260000188134. Listed at 11 retailers as of November 4, 2026, with prices from $2,176 to $5,752, a $3,576 spread on the same certified stone. NZ Jewellers lists it at $5,752. 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.
