About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded H 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 1232988847. Listed at 15 retailers as of October 30, 2026, with prices from $5,957 to $13,037, a $7,080 spread on the same certified stone. NZ Jewellers lists it at $13,037. 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.
