About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7516520911. Listed at 11 retailers as of November 4, 2026, with prices from $6,784 to $13,010, a $6,226 spread on the same certified stone. NZ Jewellers lists it at $13,010. 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.
