About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2537584062. Listed at 10 retailers as of November 5, 2026, with prices from $3,298 to $6,869, a $3,572 spread on the same certified stone. NZ Jewellers lists it at $6,869. 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.
