About this 1.23ct natural marquise diamond

This 1.23ct 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 6552471563. Listed at 16 retailers as of November 5, 2026, with prices from $8,850 to $18,735, a $9,885 spread on the same certified stone. NZ Jewellers lists it at $18,735. 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.
