British Masonic Signet Ring In 9ct Gold With Onyx, Birmingham 1976

A classic British Masonic signet ring crafted in 9ct gold and set with a polished black onyx panel. The stone is inlaid with a gold square and compass emblem centred with the letter “G”.

The clean signet form features a strong rectangular head and smooth tapering shoulders, giving the ring a balanced and timeless appearance. The contrast between the deep black onyx and the gold inlay highlights the precise geometry of the Masonic symbol.

Hallmarked at the Birmingham Assay Office in 1976, the ring carries the sponsor’s mark C.G. for Charles Green & Son Ltd. Manufacture is attributed to The Albion Chain Co (Frank & Walter Hayes Rabone), a long-established Birmingham jewellery maker.
