About this 0.8ct natural emerald diamond

This 0.8ct natural emerald sits in the just-under-one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of October 30, 2026, with prices from £656 to £915, a £259 spread on the same certified stone. Helzberg Diamonds lists it at £915. 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.
