About this 1.09ct lab-grown emerald diamond

This 1.09ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG770643692 or 770643692. Listed at 20 retailers as of November 1, 2026, with prices from $324 to $1,750, a $1,426 spread on the same certified stone. Brilliant Earth lists it at $1,750. 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.
