About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5496178579. Listed at 9 retailers as of October 30, 2026, with prices from $4,319 to $10,058, a $5,739 spread on the same certified stone. NZ Jewellers lists it at $10,058. 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.
