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 I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2506368685. Listed at 13 retailers as of October 28, 2026, with prices from £1,325 to £3,439, a £2,114 spread on the same certified stone. NZ Jewellers lists it at £3,439. 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.
