About this 1.73ct lab-grown emerald diamond

This 1.73ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6481287887. Listed at 18 retailers as of October 27, 2026, with prices from $511 to $2,733, a $2,222 spread on the same certified stone. Brilliant Earth lists it at $2,733. 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.
