About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 737595428. Listed at 15 retailers as of October 30, 2026, with prices from $1,217 to $3,216, a $1,999 spread on the same certified stone. NZ Jewellers lists it at $3,216. 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.
