About this 1.7ct natural emerald diamond

This 1.7ct natural emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6431263947. Listed at 3 retailers as of October 25, 2026, with a relatively tight 9% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
