9 Facts About Aurora Borealis Antique or Not.


It's not uncommon to find "antique" in the description of a piece of jewelry containing aurora borealis beads or stones. Sometimes the circa date listed will be way before the technique was even invented. I don't think the author means to mislead. More than likely they have been misinformed. The uneducated reader will assume it's true. "It's on the Internet, it must be true." Right? Wrong!

Since I am a witness to this crime of misinformation, it is my duty to report the crime to the proper authorities. You know I'm kidding don't you. While this isn't necessarily a felony or even a misdemeanor, it should not be taken lightly. The monetary value of an item depends on an item being correctly identified.

So here are facts about Aurora Borealis. I'll even back up what I'm saying with a link to an article written by an expert in costume jewelry. Matter of fact she has even written a book on the subject maybe you've heard of it, Warman's Costume Jewelry, Identification and Price Guide.


Fact #1
Aurora Borealis is sometimes listed as AB.
Fact #2
Manfred Swarovski and Christian Dior invented the process in 1955.
Fact #3
The process involves layering thin metal over glass in a steam vacuum, producing a magnificent, sparkling, iridescent finish.
Fact #4
Swarovski produced optical products for the military starting in 1939. Stone shipments out of Austria during this time were highly limited,
Fact #5
Aurora Borealis  mistakenly gets attributed to earlier beads with an iridescent finish.
Fact #6
The high quality Aurora Borealis rhinestones produced by Swarovski were widely used in costume jewelry manufacture in the late 50s through early 60s.
Fact #7
AB has been wrongly labeled as "carnival glass."
Fact #8
The aurora borealis seen in today's costume jewelry, doesn't begin to compare to the quality of the originals.
Fact #9
The brand became the name. Like Jello, Band-Aid or Kleenex. Or Vaseline, Q-tips and Post-its. Aurora Borealis has become the name for iridescent finish in costume jewelry.
