This 0.31ct lab-grown emerald sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG801699178 or 801699178. Listed at 19 retailers as of October 29, 2026, with prices from $204 to $1,184, a $981 spread on the same certified stone. MOH London lists it at $1,184. 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.
