18K gold ring with a large cushion-shaped tourmaline, designed as a bold vintage-style statement ring with a substantial yellow gold band and a prominent central gemstone setting. The ring is set with a 4.84 ct tourmaline displaying a deep dark green to green-black appearance, with visible reflective facets and a strong polished surface. The stone has a rounded cushion outline and is mounted in a smooth bezel-style setting that gives the piece a solid, sculptural look. The ring has a total weight of 6.89 g and an inner diameter of 22 mm. Based on the inner diameter, the approximate inner circumference is 69.12 mm, calculated as 22 × π = 69.12 mm. This corresponds approximately to ring size EU 69, depending on the sizing system and exact fit. The broad shank and heavier gold construction give the ring a substantial presence on the hand, suitable for collectors of vintage gold jewelry, gemstone rings, men’s rings, signet-style rings, and statement cocktail rings. The design combines a polished yellow gold body with a large dark tourmaline centre stone, creating strong contrast between the warm gold tone and the deep green gemstone. The shoulders of the ring are wide and slightly tapered toward the central setting, giving the piece a classic vintage profile with a bold, masculine character while still being wearable as a unisex gemstone ring.
