About this 1.2ct natural emerald diamond

This 1.2ct natural emerald sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1557542620. Listed at 7 retailers as of November 4, 2026, with prices from £2,178 to £4,102, a £1,924 spread on the same certified stone. With Clarity lists it at £4,102. 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.
