Corvidae Antique has dated this piece to the Victorian era.

There are no hallmarks but the ring has been fully tested. Fifteen-carat gold pieces are not overly common (in the UK only really used between 1854 and 1932) and as this fineness was generally used in high quality pieces, it is attractive to collectors.
Size: O (UK), 7-7.5 (US).
The face of the ring measures 2.7 x 2cm, the sapphire is approx 9 x 6mm.
Weight: 4.7g.
