(You save )

Rendered in 18 Ct gold and platinum, this equestrian themed brooch is in the form of a Polo Mallet or possibly a riding crop brooch. Circa 1900, it's set with a beautiful line of uninterrupted sparking rubies (channel set) and topped with an Old Mine Cut diamond set in platinum. The flashes of red and hot pink make it a standout against a black blazer or black dress.

During the 19th and early 20th centuries, hunting was known as the sport of kings and this extended to the landed aristocracy. Equestrian themed sports were at the center of the fall and winter social season and generated all sorts of social events.

During the hunting season, lunches, dinners, and balls all required a specific dress and accessories. This, in part, drove the appetite for equestrian themed jewelry.
