About this 1.8ct natural emerald diamond

This 1.8ct natural emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6565017642. Listed at 7 retailers as of November 1, 2026, with prices from £6,181 to £11,884, a £5,703 spread on the same certified stone. With Clarity lists it at £11,884. 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.
