About this 0.91ct natural emerald diamond

This 0.91ct natural emerald sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 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 £1,525 to £1,888, a £363 spread on the same certified stone. Blue Nile lists it at £1,888. 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.
