About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded J 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 7563567361. Listed at 22 retailers as of November 5, 2026, with prices from £1,157 to £3,331, a £2,175 spread on the same certified stone. NZ Jewellers lists it at £3,331. 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.
