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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6531195008. Listed at 15 retailers as of November 4, 2026, with prices from £2,702 to £5,916, a £3,214 spread on the same certified stone. NZ Jewellers lists it at £5,916. 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.
