About this 0.78ct natural emerald diamond

This 0.78ct natural emerald sits in the just-under-one-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 5563434551. Listed at 5 retailers as of October 28, 2026, with prices from €909 to €1,133, a €224 spread on the same certified stone. Blue Nile lists it at €1,133. 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.
