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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3515567826. Listed at 20 retailers as of October 30, 2026, with prices from £1,425 to £3,641, a £2,217 spread on the same certified stone. NZ Jewellers lists it at £3,641. 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.
