About this 3ct lab-grown emerald diamond

This 3ct lab-grown emerald sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG564384617 or 564384617. Listed at 12 retailers as of November 5, 2026, with prices from £257 to £1,244, a £987 spread on the same certified stone. MOH London lists it at £1,244. 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.
