About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1429196516. Listed at 21 retailers as of October 30, 2026, with prices from $5,939 to $13,454, a $7,515 spread on the same certified stone. NZ Jewellers lists it at $13,454. 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.
