A magnificent piece featuring a moonstone of over 20 carats, sizable rose cut and old mine cut diamonds, and pink sapphires.

An outstanding specimen of late 19th century American craftspersonship in solid 18ct.  A black enamel band surrounds the face. The eye-catching center stone in this brooch enchants the viewer with both adularescence and asterism, or the starburst effect- an optical reflectance effect seen in certain gemstones, such as this one. 

This type of geometry in jewelry was exemplified and celebrated especially in England and France around the 1860s, and expanded upon in American jewelry the following decade. For instance, the outer layer of diamonds alternate between rose-cut & chunky old mine cut diamonds, introducing a geometric experience. This brooch also has a suspension hook, allowing it to be used as a pendant if desired.
