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 $2,478 to $6,016, a $3,538 spread on the same certified stone. NZ Jewellers lists it at $6,016. 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.
