About This Colombian Emerald:
A vivid green Colombian emerald weighing 4.20 carats, cut in a classic rectangular shape. Its color and clarity are largely natural, with only minor traditional oiling — a centuries-old method that gently enhances brilliance without changing the stone’s true appearance.
Unlike modern resins or heavy treatments, this subtle oiling preserves the emerald’s authenticity. Certified by AGL as Colombian in origin, this stone showcases the world-famous saturation and “jardin” inclusions that make Colombian emeralds the most sought-after.
A rare gem combining natural beauty, minimal enhancement, and certified pedigree.

One of One
Most jewelry is made to be sold many times over. Ours isn't. We source rare vintage and estate watches you won't find in a display case anywhere else, and what we don't source, we make ourselves. Either way, the piece in front of you is singular, not pulled from a production run. When you buy from Assay, chances are no one else on earth owns its twin.
Featured on...
At Assay, we’re proud to be featured as top sellers across multiple marketplaces (1st Dibs, Chrono24, Etsy, Rubylane and more). No matter where you prefer to shop, you’ll find the same exceptional products and service available on every platform!
