About this 1.23ct natural oval diamond

This 1.23ct natural oval sits in the classic one-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 801637980. Listed at 12 retailers as of November 5, 2026, with prices from $4,160 to $8,162, a $4,002 spread on the same certified stone. NZ Jewellers lists it at $8,162. 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.
