About this 1.3ct natural emerald diamond

This 1.3ct natural emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded J 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 2566244095. Listed at 6 retailers as of October 28, 2026, with prices from £1,605 to £2,005, a £401 spread on the same certified stone. Blue Nile lists it at £2,005. 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.
