About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded I 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 2467377630. Listed at 20 retailers as of October 30, 2026, with prices from $4,558 to $10,021, a $5,462 spread on the same certified stone. NZ Jewellers lists it at $10,021. 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.
