About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7562025950. Listed at 23 retailers as of October 30, 2026, with prices from £1,087 to £3,494, a £2,407 spread on the same certified stone. NZ Jewellers lists it at £3,494. 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.
