About this 2.5ct natural emerald diamond

This 2.5ct natural emerald sits in the two to three carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of October 29, 2026, with prices from £16,464 to £19,505, a £3,041 spread on the same certified stone. Blue Nile lists it at £19,505. 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.
