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 £2,135 to £4,190, a £2,055 spread on the same certified stone. NZ Jewellers lists it at £4,190. 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.
