About this 1.56ct natural heart diamond

This 1.56ct natural heart sits in the one-and-a-half to two 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 250000054643. Listed at 12 retailers as of October 30, 2026, with prices from $6,311 to $12,103, a $5,793 spread on the same certified stone. NZ Jewellers lists it at $12,103. 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.
