About this 1.2ct natural oval diamond

This 1.2ct 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 6237693749. Listed at 21 retailers as of November 5, 2026, with prices from £3,138 to £7,247, a £4,109 spread on the same certified stone. NZ Jewellers lists it at £7,247. 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.
