About this 1.8ct natural emerald diamond

This 1.8ct natural emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1563480625. Listed at 5 retailers as of November 3, 2026, with prices from $14,862 to $18,596, a $3,734 spread on the same certified stone. Blue Nile lists it at $18,596. 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.
