About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD �26031390002. Listed at 9 retailers as of November 5, 2026, with prices from $3,601 to $6,799, a $3,198 spread on the same certified stone. NZ Jewellers lists it at $6,799. 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.
