11th-13th century. Size 7 1/4 with rounded face tapered band. Raised oval bezel cut with four hatched bands enclosing a diamond, probably serving as a signet ring to seal wax and clay replacing an inked signature. Made by with a central core which would distribute the flowing metal and heat evenly. The core was then laboriously removed by hand and the inside of the ring polished. The remnants of the core are clear in this ring. Professionally refurbished with the 24karat gold surface restored. Gift boxed with a certificate of authenticity. Good wearable size.
