About this 1.09ct lab-grown emerald diamond

This 1.09ct lab-grown emerald sits in the classic one-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 7491482148. Listed at 4 retailers as of November 4, 2026, with prices from £463 to £550, a £87 spread on the same certified stone. Zales lists it at £550. 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.
