Very striking silver brooch by Alexander Ritchie, from the late 1920s/early 1930s period. The central stone is flanked by two Celtic bird heads. The stone is no doubt one that Ritchie found on one of the many small Iona beaches, and appears to be an opaque variegated brown quartz, rather than the dark green Iona marble. Approximate dimensions 4.6 x 2 cms. An unusual and attractive Iona piece, the reverse markings being AR and IONA. No hallmark (not uncommon for Ritchie's Iona work), although made from sterling silver.
