About this 1.45ct lab-grown emerald diamond

This 1.45ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818660255 or 818660255. Listed at 8 retailers as of October 28, 2026, with prices from $947 to $5,412, a $4,465 spread on the same certified stone. Rare Carat lists it at $5,412. 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.
