About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded I 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 1545354362. Listed at 22 retailers as of November 4, 2026, with prices from $4,470 to $10,852, a $6,382 spread on the same certified stone. NZ Jewellers lists it at $10,852. 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.
