These glass pieces are what inspired me to become a uranium glass jewelry designer. I have never seen their like.
They were probably meant to be some kind of brooch. Made in 1930s Czechoslovakia, they are about an inch and a half in length. Due to their age they have a few nips here and there but all are structurally sound and in amazing condition for their age.
They came in their original tissue wrapping from the factory. On an 18 inch silver chain. Feel free to check out my other uranium glass jewelry items for sale.
I do custom commissions so don't hesitate to contact me if you are looking for something specific. Uranium glass is glass made with up to 2% uranium dioxide for color. The uranium content causes the glass to fluoresce bright green under a UV blacklight.
Uranium dioxide was added to glass because it produces brilliant, beautiful colors unmatched by any other glassmaking method. I strive to create and source jewelry that looks as beautiful in natural light as it does under a blacklight. Uranium glass is identified with a UV blacklight, and it's only uranium glass if the item is truly glass, not another material, and fluoresces the telltale bright neon green. If a piece of glass glows bright green in UV light then it contains uranium.
No other material or element in glass has that effect. Other jewelry components such as resin, plasic, enamel, paint, acrylic, glow-in-the-dark materials, some gemstones, and even adhesive can fluoresce green like uranium, so it is imperative for a collector of such glass in jewelry to make sure the glowing item is truly glass. Sometimes an item can glow a dull green rather than bright neon green, and that is due to manganese rather than uranium. The uranium glass in jewelry is the same glass found in the depression-era glassware that is popular with collectors.I treasure hunt all over the world for vintage uranium glass pieces to use in my jewelry, as well as new pieces from Czech Republic. I specialize in sourcing old art deco jewelry components and faceted glass stones. I also very much enjoy finding vintage uranium glass jewelry pieces. All of my own pieces are made with the greatest care and love and have a lifetime guarantee for repair, including free replacement of damage/loss to the glass stones. I take great care to ensure that all of my items are true uranium glass.
Please note that because my rings are glass they are susceptible to breakage and may not be suitable for every day wear. Despite this, I have great reports from thousands of my customers on the longevity. If you are interested in a ring for daily wear such as an engagement or wedding ring, but are concerned about breakage, I highly recommend one of my spinel rings. The spinels I use look like and glow green just like uranium, but are much more durable because they are gemstones. Please don't hesitate to message me with questions!
Many of my pieces I make by hand to order for each customer, therefore, sometimes my processing times can vary when life happens or there are issues with my suppliers.
