Everyone has a learning curve, when it comes to recognizing costume jewelry stones. It can be especially hard to learn to distinguish between types of “white” of clear stones. But that being said, I think some dealers who have been in the costume jewelry sales business for years are either incredibly lazy (for failing to learn what stones they sell) or downright deceiving.
I don’t want you to get caught by my biggest pet peeve: when a dealer lists a rhinestone or crystal as “cubic zirconia.”
No matter when I look online and do a search for vintage cubic zirconia jewelry on popular selling platforms like Ebay, Etsy, and Ruby Lane, I find at least one if not more dealers listing pre 1970s pieces containing cubic zirconia. This makes my blood boil.
Here is my biggest tell for you: Nothing and I mean Nothing has cubic zirconia stones if it was made prior to 1976.
Why? Because cubic zirconia is a made-in-the-laboratory diamond simulant developed in the 1960s. And Cubic Zirconia jewelry was not available to the general public until 1976.
Just like the first mass produced aurora borealis coated costume jewelry was made available to the public in 1955. But back to cubic zirconia……….
Knowing the 1976 mass production date for costume jewelry with cubic zirconia will help you in two ways:
Now, we have established that pieces made prior to 1976 must contain rhinestones, plain glass or crystals. But how do you tell if a piece of costume jewelry from the 1970s or later has cubic zirconia, rhinestones, plain glass or crystals? We’ll cover that in another blog article!
Do you have a favorite piece of cubic zirconia jewelry? If so, please tell us about it in the comments section. Also, if you love fashion and vintage jewelry as much as I do, subscribe to this blog so you don't miss an article!
