About this 5.03ct lab-grown emerald diamond

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 LG692505550 or 692505550. Listed at 3 retailers as of October 30, 2026, with prices from £1,926 to £3,642, a £1,717 spread on the same certified stone. Kay Jewelers lists it at £3,642. 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.
