About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1545136997. Listed at 10 retailers as of November 2, 2026, with prices from $2,875 to $7,187, a $4,312 spread on the same certified stone. NZ Jewellers lists it at $7,187. 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.
