About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1563527470. Listed at 20 retailers as of November 5, 2026, with prices from $4,500 to $9,747, a $5,247 spread on the same certified stone. NZ Jewellers lists it at $9,747. 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.
