This 1.5ct natural emerald sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 546209711. Listed at 11 retailers as of November 5, 2026, with prices from £1,756 to £4,101, a £2,345 spread on the same certified stone. NZ Jewellers lists it at £4,101. 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.
