About this 3.9ct lab-grown emerald diamond

This 3.9ct lab-grown emerald sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849637365 or 849637365. Listed at 6 retailers as of October 27, 2026, with prices from £333 to £1,740, a £1,407 spread on the same certified stone. With Clarity lists it at £1,740. 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.
