About this 4.12ct lab-grown emerald diamond

This 4.12ct lab-grown emerald sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG833668480 or 833668480. Listed at 6 retailers as of October 29, 2026, with prices from $4,484 to $25,306, a $20,822 spread on the same certified stone. Mervis Diamond Importers lists it at $25,306. 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.
