Medieval green glass ring, circa 14th-15th century. Set horizontally to centre with original green glass in a closed back rubover collet setting on a rectangular bezel with cablework decoration flanked by shoulders engraved with cruciform pattern to a flat shank. Tested yellow gold, approximately 1.9g in weight, circa 14th-15th century.
It is likely that the green glass set in this ring was intended to imitate a costly and very rare emerald. Emeralds at the time were thought to be imbued with magical physical and mental healing powers and so were highly sought after and prized. The green glass set in this ring was meticulously crafted to look like an emerald both in terms of colour and inclusions within the glass. The fact that this emerald imitation was set in such an intricately designed mount adds to the conclusion that it was possibly sold in the 14th to 15th century as a genuine emerald ring for a fortune.
