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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2434522791. Listed at 23 retailers as of October 28, 2026, with prices from $10,748 to $20,097, a $9,349 spread on the same certified stone. NZ Jewellers lists it at $20,097. 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.
