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 $4,543 to $9,552, a $5,008 spread on the same certified stone. NZ Jewellers lists it at $9,552. 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.
