This 1.21ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 809692830. Listed at 6 retailers as of November 2, 2026, with prices from $3,010 to $5,855, a $2,845 spread on the same certified stone. NZ Jewellers lists it at $5,855. 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.
