About this 1.3ct natural oval diamond

This 1.3ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 808620135. Listed at 12 retailers as of November 4, 2026, with prices from $2,448 to $6,555, a $4,107 spread on the same certified stone. NZ Jewellers lists it at $6,555. 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.
