How do I clean an antique ruby ring?

Use warm soapy water and a soft-bristled brush to gently remove oils from beneath the stones. Avoid harsh chemical dips or ultrasonic cleaners, particularly if the piece incorporates pearls. Pat the ring completely dry with a lint-free cloth before storing it separately from harder jewellery items.

Are rubies treated in these pieces?

Historical stones from nineteenth and early twentieth-century sources often present natural characteristics without modern heat enhancement or clarity treatments. Many high-value pieces from Burma feature unheated origin reports issued by gemmological laboratories. Examining the internal inclusions under magnification helps reveal the untreated geological origin of the ruby.

How do I identify the date of my ring?

British pieces carry hallmark stamps indicating the assay office, such as Chester or Birmingham, alongside a specific date letter. Comparing these punches against official assay registers reveals the exact year the metal was tested and marked. Stylistic cues like navette shapes or starburst engravings also help narrow down the manufacturing decade when hallmarks are worn.
