Antique and vintage emerald rings in period settings from Georgian to Art Deco. Emerald — green beryl coloured by chromium and vanadium — sits at Mohs 7.5–8 on the hardness scale, making it softer than sapphires and rubies. Antique jewellers accommodated this with protective settings: the emerald cut itself, with its truncated corners, was developed around the 1500s specifically to reduce this stone's vulnerability to sharp impacts.
The internal characteristics known as jardin — fractures, mineral crystals, and liquid-filled cavities that form a garden-like landscape under magnification — are expected in natural emeralds and help confirm origin. Colombian stones, dominant since the sixteenth-century Spanish conquest, show warm pure-green tones with distinctive three-phase inclusions. Oiling with cedarwood oil or Canada balsam to improve clarity has been accepted practice since Pliny documented it in the first century, and is routine in antique emeralds without diminishing their authenticity.
Queen Victoria's 1839 emerald serpent engagement ring established the stone as a romantic choice. In Victorian acrostic jewellery, emerald serves as the "E" in both REGARD and DEAREST. Settings range from Georgian closed-back gold collets through Victorian open-back claw mounts to Art Deco calibré-cut platinum designs.
