About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI 788644178. Listed at 9 retailers as of November 5, 2026, with prices from $1,175 to $3,075, a $1,900 spread on the same certified stone. NZ Jewellers lists it at $3,075. 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.
