This 5.03ct lab-grown emerald sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG733543928 or 733543928. Listed at 17 retailers as of October 30, 2026, with prices from £378 to £2,702, a £2,324 spread on the same certified stone. Brilliant Earth lists it at £2,702. 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.
