About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3565212465. Listed at 18 retailers as of November 5, 2026, with prices from £1,189 to £3,338, a £2,149 spread on the same certified stone. NZ Jewellers lists it at £3,338. 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.
