About this 1.2ct natural oval diamond

This 1.2ct natural oval 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 737520280. Listed at 7 retailers as of November 2, 2026, with prices from $2,118 to $4,945, a $2,827 spread on the same certified stone. NZ Jewellers lists it at $4,945. 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.
