This 6.51ct lab-grown emerald sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG645459294 or 645459294. Listed at 22 retailers as of October 29, 2026, with prices from $1,469 to $15,047, a $13,578 spread on the same certified stone. Brilliant Earth lists it at $15,047. 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.
