About this 1.31ct natural emerald diamond

This 1.31ct natural emerald sits in the one-and-a-quarter to one-and-a-half 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 2558707657. Listed at 6 retailers as of November 4, 2026, with prices from £1,379 to £2,600, a £1,221 spread on the same certified stone. With Clarity lists it at £2,600. 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.
