About this 3.7ct lab-grown emerald diamond

This 3.7ct lab-grown emerald sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG683509187 or 683509187. Listed at 22 retailers as of November 1, 2026, with prices from $1,125 to $12,032, a $10,907 spread on the same certified stone. Brilliant Earth lists it at $12,032. 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.
