About this 1ct natural oval diamond

This 1ct 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 7421642194. Listed at 17 retailers as of November 5, 2026, with prices from £805 to £2,777, a £1,972 spread on the same certified stone. NZ Jewellers lists it at £2,777. 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.
