About this 1.5ct natural emerald diamond

This 1.5ct natural emerald sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 729536801. Listed at 19 retailers as of October 30, 2026, with prices from £2,020 to £4,715, a £2,695 spread on the same certified stone. NZ Jewellers lists it at £4,715. 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.
