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 standard cut grade stated by the retailer rather than the lab and certified by GIA 7501790257. Listed at 16 retailers as of November 5, 2026, with prices from €3,154 to €6,893, a €3,739 spread on the same certified stone. NZ Jewellers lists it at €6,893. 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.
