About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 729536797. Listed at 14 retailers as of October 27, 2026, with prices from £2,196 to £4,311, a £2,114 spread on the same certified stone. NZ Jewellers lists it at £4,311. 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.
