This 0.45ct 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 LG741519227 or 741519227. Listed at 12 retailers as of October 30, 2026, with prices from $428 to $2,999, a $2,571 spread on the same certified stone. Zales lists it at $2,999. 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.
