The zigzag style of these earrings is informed by my other hobby. I am also an Extra Class Amateur Radio Operator and this pattern matches the industry symbol for transistors, essential to my operations, including bouncing signals off the moon! The crystals are of the finest quality manufactured by Europe's most famous crystal manufactures. Alas, they no long make these crystal beads and forbid the use of their name, and even their country, in our ads. A simple search would reveal their name.
