Female old sxe free chat - Dating vintage clasps
Whether updating a collection, searching for information about a family heirloom, or assisting a colleague or customer, dating a piece of vintage costume jewelry can present a challenge.
Many tools and techniques are familiar to the experienced collector, including dating by textured versus smooth back casting, extended pin stems and simple “C” closures, the presence of a copyright symbol, the use of aurora borealis rhinestones, to name but a few.

Trifari and Coro advertised extensively during the 1950s, 1960s and 1970s, as did many other costume jewelry companies.
The Palm Royale brooch and earrings design pictured below was found in a vintage advertisement that appeared in “Charm” magazine in December 1946.
However, determining findings popularly used is possible.
For example, in looking at the use of clip-back and the use of screw-back findings for earrings, a survey of those currently for sale found that from 1950 through 1955, screw-backs were used about 30% of the time, and clip-backs 70 percent of the time.
Prior to the early 1950s, typical necklace clasp styles used by Coro and Trifari were spring ring, push (also known as box), or fold-over.
