About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2546873498. Listed at 19 retailers as of November 2, 2026, with prices from £1,425 to £3,910, a £2,485 spread on the same certified stone. NZ Jewellers lists it at £3,910. 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.
