About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556718194. Listed at 6 retailers as of November 1, 2026, with prices from $1,747 to $4,715, a $2,968 spread on the same certified stone. NZ Jewellers lists it at $4,715. 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.
