About this 1.5ct natural emerald diamond

This 1.5ct 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 standard cut grade stated by the retailer rather than the lab and certified by GIA 5453802658. Listed at 14 retailers as of October 27, 2026, with prices from £2,598 to £5,980, a £3,381 spread on the same certified stone. NZ Jewellers lists it at £5,980. 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.
