All the items from my shop are handmade. Some items are currently in stock, and others are made to order. If an item is currently in stock it will be mailed within two days. Otherwise please follow the time frame listed in each item description.


Silver and brass jewelry will darken over time and develop a patina. Periodic cleaning with a jewelry polishing cloth will keep silver jewelry white. Never use harsh chemicals to clean your jewelry such as toothpaste or jewelry cleaning solution. A soft bristled toothbrush and warm water can help remove light residue from your jewelry.

  Oxidized jewelry can become brighter with regular wear and over time will developed a silver antiqued finish. Every piece of oxidized jewelry has been sealed with a protective wax to ensure a lasting finish.

Always avoid wearing jewelry while swimming, showering and sleeping.
