About this 1.22ct natural oval diamond

This 1.22ct natural oval sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6565019307. Listed at 13 retailers as of November 2, 2026, with prices from £3,623 to £6,947, a £3,324 spread on the same certified stone. NZ Jewellers lists it at £6,947. 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.
