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 SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 762558410. Listed at 16 retailers as of November 1, 2026, with prices from $3,716 to $8,937, a $5,220 spread on the same certified stone. NZ Jewellers lists it at $8,937. 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.
