About this 1.5ct natural emerald diamond

This 1.5ct natural emerald sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6421519037. Listed at 20 retailers as of November 5, 2026, with prices from $6,738 to $15,542, a $8,804 spread on the same certified stone. Adiamor lists it at $15,542. 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.
