About this 1.8ct natural oval diamond

This 1.8ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 747550227. Listed at 19 retailers as of November 1, 2026, with prices from $13,659 to $28,078, a $14,419 spread on the same certified stone. NZ Jewellers lists it at $28,078. 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.
