      • Star BroochesStar Brooches. The stars were observed by ancient peoples thousands of years ago. They were used for navigation, time-keeping and agriculture for centuries as well as mythology and astrology, it is therefore not surprising that stars were a popular form for jewelry, including brooches. Star brooches have been in use since Roman times and possibly before, however,  it was in the Medieval age where they first began to become popular items of adornment among the wealthy.

Agate

Price guide to antique and vintage agate brooches. Agate is a variety of chalcedony, a cryptocrystalline form of quartz. Translucency, patterns of color, or moss-like inclusions may distinguish this stone from other forms of chalcedony. Agates can show a wide variety of vivid, multiple colors. These are principally the result of traces of oxides of iron, manganese, titanium, chromium, nickel, and other elements. All agates take a wonderful polish and are tough enough for most jewelry uses.
