About this 1.21ct natural marquise diamond

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 $4,234 to $8,236, a $4,002 spread on the same certified stone. NZ Jewellers lists it at $8,236. 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.
