About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1455614152. Listed at 18 retailers as of November 5, 2026, with prices from £1,316 to £3,867, a £2,551 spread on the same certified stone. NZ Jewellers lists it at £3,867. 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.
