About this 1.55ct natural heart diamond

This 1.55ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 210000080770. Listed at 9 retailers as of October 30, 2026, with prices from $12,383 to $23,980, a $11,597 spread on the same certified stone. NZ Jewellers lists it at $23,980. 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.
