Most Suffragette jewelry has a stately quality. It tends to be substantial, the better to make its statement at a rally or on the march, atop outerwear. This bijou, by contrast, is on the large side (about 2.5" x 1.5") but it's clearly a party piece.
Such a dazzling confection of diamantes with a bold emerald paste center and dancing drops tipped with faux amethysts may well have been made for celebrations after the vote came through (1920 for all women in the US and 1918 for many in the UK, 1928 for the rest). Alternatively, given its whirling form and shimmering materials, it could refer to Halley's comet, which inspired a lot of jewelry when it appeared in 1910, the last year of the Edwardian era. The design of the brooch could be characterized as transitional or early Deco, but it makes an emphatic nod to Edwardiana in those drops of staggered length. Asymettrical drops were characteristic of Edwardian necklaces known as "negligee" style (nothing to do with nightwear). Still, I'm persuaded by other details of fabrication that 1920 is more probable than 1910.
Provenance is a California estate and condition is, as you see, lovely. Great condition is more common than not for Suffragette pieces, since most saw only short-term use before becoming treasured keepsakes.
