Designed in the archaeological revival style of the 19th century, this watch chain and fob is 4.25 inches in length from end-to-end and possesses very interesting visual and tactile qualities. One side of the sphere smooth while the other features a raised beading and wire-work motif inspired by Etruscan jewelry techniques. Antique Lava Cameo depicting Mount Vernon, home of George Washington. The beads are a forest-green color with a reflective surface indicating a very high-quality finish. An off-set brooch of rhondelle rhinestones and rhondelle opaque glass forms the necklaces' focal point. It's design elements are wired together and topped with small glass end-caps. Hand carved Hawaiian black coral hand carved and polished to a high gloss. On the underside of the bracelet there is small section in which pitting natural to coral can be seen. Slight variation in the shells hints at a handmade process.

This is attached to an interesting and very attractive snake-scale chain. The cameo is in high relief and bezel set with a long pin and c-clasp. Only a few of the beads on the 18" multi-strand necklace have hand-knots in between.

It is obvious that Trifari and Coro patent information can be used to date pieces of their manufacture.

However, this information can also be used to assist with dating jewelry made by other companies.

The patented designs from a given year or a given decade show the popularity of styles, materials and themes, and indicate the types of findings and the methods of construction being used for the time period.
