About this 4.2ct lab-grown emerald diamond

This 4.2ct 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. Listed at 4 retailers as of October 29, 2026, with prices from $1,615 to $6,597, a $4,982 spread on the same certified stone. Blue Nile lists it at $6,597. 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.
