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 1485142206. Listed at 21 retailers as of November 1, 2026, with prices from £1,991 to £4,359, a £2,368 spread on the same certified stone. NZ Jewellers lists it at £4,359. 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.
