About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 737520517. Listed at 10 retailers as of October 30, 2026, with prices from £1,624 to £3,806, a £2,182 spread on the same certified stone. NZ Jewellers lists it at £3,806. 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.
