About this 1.2ct natural emerald diamond

This 1.2ct natural emerald sits in the classic 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 2548373320. Listed at 7 retailers as of November 4, 2026, with prices from £1,054 to £1,342, a £287 spread on the same certified stone. GemTrove lists it at £1,342. 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.
