About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-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 7566616712. Listed at 13 retailers as of November 5, 2026, with prices from $2,403 to $7,178, a $4,775 spread on the same certified stone. NZ Jewellers lists it at $7,178. 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.
