About this 1ct natural emerald diamond

This 1ct natural emerald sits in the classic one-carat band, graded J 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 1569004051. Listed at 6 retailers as of November 5, 2026, with prices from £742 to £1,115, a £374 spread on the same certified stone. Blue Nile lists it at £1,115. 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.
