The power of Herkimer diamond: Herkimer diamond is associated with cleansing, spiritual growth, and healing. A unique type of quartz, it has become known as the stone of atunement. The Greeks, Romans, and Egyptians all used quartz crystals as talismans and as a tool to expel negative energies.

Card: Original artwork and interesting, fun facts on the back about the power and history of each stone.

Care Instructions

Gold Plating

Our plating is a genuine fine 24k gold. The gold is applied to a base metal (brass in this case) in a very thin layer. Gold plated jewelry is an affordable option to solid gold. You can lengthen the life of the gold layer by removing your jewelry when swimming in pools and especially the ocean. Also while exercising. Salt and chemicals break down the gold layer. Do not use a polishing cloth with chemicals to clean plated jewelry as the gold will rub right off.

Sterling Silver

Silver will always oxidize over time. Silver cleaners are available in most grocery stores or pharmacies. 


Everyone loves the warm, earthy color of brass. Although brass will oxidize over time, you can always polish it up with a polishing cloth or brass cleaner.  You can also seal it with clear nail polish or a jewelry sealer and that will prevent it from tarnishing.
