About this 1.22ct natural oval diamond

This 1.22ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7501971658. Listed at 19 retailers as of November 5, 2026, with prices from $3,888 to $8,421, a $4,533 spread on the same certified stone. NZ Jewellers lists it at $8,421. 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.
