This 0.7ct lab-grown emerald sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG520298410 or 520298410. Listed at 19 retailers as of October 29, 2026, with prices from $123 to $1,415, a $1,292 spread on the same certified stone. MOH London lists it at $1,415. 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.
