This 0.42ct 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 LG764675461 or 764675461. Listed at 11 retailers as of October 28, 2026, with prices from £170 to £1,186, a £1,017 spread on the same certified stone. Zales lists it at £1,186. 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.
