An an amazing and extraordinarily rare Victorian brooch depicting a bulldog jumping through a golden hoop to catch his natural pearl "ball." The dog is set "en tremblant" with a spring mechanism so the slightest movement causes the dog to move and the diamonds to glitter. The rose cut and old mine cut diamonds are of unusually good quality with bright color and very good clarity. As is typical of the period, the diamonds are set in silver with gold backing in places where it rub against clothing. The ears, collar and hoop are worked in rose gold. The eye is set with a ruby. Pins of this era sometimes had a separate stick pin element that were intended to be a sort of safety mechanism, but in this case it becomes part of the story! The reverse is stamped with French 18K marks and with "Depose" marks indicating that the design was patented. High-quality diamond pave animal brooches from the Victorian era are quite desirable, but the trembler mechanism makes this piece an extraordinary find.
