About this 1.57ct natural emerald diamond

This 1.57ct natural emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1435921863. Listed at 20 retailers as of October 30, 2026, with prices from £2,376 to £4,996, a £2,620 spread on the same certified stone. NZ Jewellers lists it at £4,996. 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.
