About this 0.77ct natural emerald diamond

This 0.77ct natural emerald sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566462352. Listed at 5 retailers as of October 28, 2026, with prices from £840 to £1,049, a £209 spread on the same certified stone. Blue Nile lists it at £1,049. 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.
