About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7558072766. Listed at 7 retailers as of November 5, 2026, with prices from £1,265 to £1,855, a £591 spread on the same certified stone. Blue Nile lists it at £1,855. 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.
