About the Setting:
The 18k white or yellow gold bezel setting is crafted with precision to frame the emerald’s step-cut facets in clean, uninterrupted lines. Its smooth, high-polish finish reflects light around the gem, amplifying the brilliance of the green tones. The shank is thick and sculptural, designed for both strength and elegance, providing balance to the substantial 4.20 carat center stone. This made-to-order construction allows for subtle customization in size while maintaining a timeless, architectural profile that suits both modern and vintage-inspired tastes.
About the Stone:
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.
