About this 1.03ct natural emerald diamond

This 1.03ct natural emerald sits in the classic 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 2556785782. Listed at 5 retailers as of October 30, 2026, with prices from £1,259 to £1,510, a £251 spread on the same certified stone. Blue Nile lists it at £1,510. 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.
