About this 0.75ct natural emerald diamond

This 0.75ct natural emerald sits in the just-under-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 2566511158. Listed at 5 retailers as of November 4, 2026, with prices from £769 to £977, a £208 spread on the same certified stone. Blue Nile lists it at £977. 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.
