About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6227965858. Listed at 21 retailers as of October 29, 2026, with prices from £2,859 to £6,375, a £3,516 spread on the same certified stone. NZ Jewellers lists it at £6,375. 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.
