About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552423903. Listed at 20 retailers as of November 5, 2026, with prices from $7,273 to $16,262, a $8,989 spread on the same certified stone. NZ Jewellers lists it at $16,262. 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.
