About this 0.9ct natural emerald diamond

This 0.9ct natural emerald sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6532975475. Listed at 6 retailers as of November 4, 2026, with prices from £456 to £839, a £383 spread on the same certified stone. GemTrove lists it at £839. 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.
