About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI 809605757. Listed at 20 retailers as of November 1, 2026, with prices from $4,278 to $10,337, a $6,059 spread on the same certified stone. NZ Jewellers lists it at $10,337. 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.
