18ct Yellow Gold Black Opal Ring

A striking 18ct yellow gold ring set with an exceptional oval cabochon black opal, shimmering with flashes of blue, green, and violet across its dark body tone. The opal is securely bezel-set within a sleek, understated mount that allows its natural play of colour to command attention.

Beautifully made by A. Bros, this piece bears a clear UK 18ct gold mark and showcases the refined craftsmanship typical of the maker. Likely dating to the late 1930s, the ring combines elegant proportions with an effortlessly modern aesthetic that remains timeless.
