About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1519240476. Listed at 22 retailers as of November 4, 2026, with prices from $5,863 to $13,288, a $7,425 spread on the same certified stone. NZ Jewellers lists it at $13,288. 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.
