About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7421090080. Listed at 21 retailers as of November 5, 2026, with prices from $7,621 to $15,551, a $7,930 spread on the same certified stone. NZ Jewellers lists it at $15,551. 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.
