Large Rhinestone Aurora Borealis Snowflake Brooch

A very pretty rhinestone vintage brooch recently arrived from USA.  Set in rivetted gold tone metal with a vibrant combination of clear rhinestones with aurora borealis light that reflects a rainbow of colours, and tear drop shaped aqua coloured rhinestones, each one prong set and fully faceted. Quite substantial in size at 7cms across, and a firm roll over safety clasp to the back.  In very good condition, a 1960's era piece gift boxed by Vintageonline.
