About this 1.8ct lab-grown emerald diamond

This 1.8ct lab-grown 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 1509866172. Listed at 2 retailers as of October 29, 2026, with prices from $1,056 to $2,697, a $1,641 spread on the same certified stone. MOH London lists it at $2,697. 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.
