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 790611310. Listed at 14 retailers as of November 1, 2026, with prices from $2,285 to $6,337, a $4,052 spread on the same certified stone. NZ Jewellers lists it at $6,337. 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.
