About this 3.66ct lab-grown emerald diamond

This 3.66ct lab-grown emerald sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of October 31, 2026, with prices from £982 to £2,412, a £1,431 spread on the same certified stone. Blue Nile lists it at £2,412. 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.
