About this 1.66ct lab-grown emerald diamond

This 1.66ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6495437575. Listed at 10 retailers as of October 28, 2026, with a 260% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
