About this 0.66ct natural emerald diamond

This 0.66ct natural emerald sits in the half to three-quarter 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 6551517812. Listed at 4 retailers as of November 2, 2026, with prices from $687 to $872, a $185 spread on the same certified stone. 77 Diamonds lists it at $872. 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.
