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 7561644639. Listed at 20 retailers as of November 6, 2026, with prices from £2,208 to £5,203, a £2,994 spread on the same certified stone. NZ Jewellers lists it at £5,203. 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.
