About this 1.01ct natural oval diamond

This 1.01ct 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 5231143252. Listed at 23 retailers as of November 5, 2026, with prices from £1,524 to £3,979, a £2,455 spread on the same certified stone. NZ Jewellers lists it at £3,979. 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.
