About this 3.06ct lab-grown emerald diamond

This 3.06ct lab-grown emerald sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG680591773 or 680591773. Listed at 10 retailers as of October 30, 2026, with prices from £253 to £1,008, a £755 spread on the same certified stone. NZ Jewellers lists it at £1,008. 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.
