About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7551551592. Listed at 30 retailers as of November 3, 2026, with prices from $6,663 to $14,934, a $8,271 spread on the same certified stone. NZ Jewellers lists it at $14,934. 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.
