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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545963748. Listed at 7 retailers as of October 30, 2026, with prices from $2,120 to $5,664, a $3,544 spread on the same certified stone. NZ Jewellers lists it at $5,664. 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.
