About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 713504316. Listed at 15 retailers as of November 5, 2026, with prices from $1,735 to $4,586, a $2,850 spread on the same certified stone. NZ Jewellers lists it at $4,586. 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.
