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 585319651. Listed at 17 retailers as of November 5, 2026, with prices from $2,242 to $6,138, a $3,896 spread on the same certified stone. NZ Jewellers lists it at $6,138. 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.
