About this 1ct natural marquise diamond

This 1ct 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 6561364401. Listed at 19 retailers as of November 5, 2026, with prices from $2,503 to $7,023, a $4,520 spread on the same certified stone. NZ Jewellers lists it at $7,023. 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.
