About this 0.8ct natural emerald diamond

This 0.8ct natural emerald sits in the just-under-one-carat band, graded I 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 5566162948. Listed at 6 retailers as of October 31, 2026, with prices from £543 to £672, a £128 spread on the same certified stone. Blue Nile lists it at £672. 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.
