Date: Circa 1915

This antique bicycle brooch is excellent quality, set with an impressive ruby displaying fine colour and brilliance.

The feature diamond set into the bar presents a lower clarity grade, however, it enhances the design with added contrast and distinctive character; this stone brings the overall average clarity of the supporting diamonds to P1 and displays some natural black inclusions, while the remaining stones predominantly bear no black inclusions.

This antique diamond brooch is an excellent gauge of gold and is in excellent condition with clear hallmarks to the reverse.
