About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 648401560. Listed at 16 retailers as of November 5, 2026, with prices from $2,343 to $5,422, a $3,080 spread on the same certified stone. NZ Jewellers lists it at $5,422. 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.
