About this 0.78ct natural emerald diamond

This 0.78ct natural emerald sits in the just-under-one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6565004279. Listed at 5 retailers as of October 30, 2026, with prices from £562 to £814, a £252 spread on the same certified stone. GemTrove lists it at £814. 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.
