This 9.51ct 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 LG797699427 or 797699427. Listed at 9 retailers as of October 29, 2026, with prices from £1,156 to £11,605, a £10,450 spread on the same certified stone. Brilliant Earth lists it at £11,605. 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.
