About this 4.21ct lab-grown emerald diamond

This 4.21ct lab-grown emerald sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7478089824. Listed at 4 retailers as of October 28, 2026, with prices from £1,754 to £3,329, a £1,575 spread on the same certified stone. Zales lists it at £3,329. 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.
