About this 1.2ct natural oval diamond

This 1.2ct 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 5516826748. Listed at 21 retailers as of October 30, 2026, with prices from $4,548 to $9,854, a $5,306 spread on the same certified stone. NZ Jewellers lists it at $9,854. 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.
