This Striped Pink Agate Gemstone is a 925 Sterling Silver Handmade Pendant that is 2.2" in size and comes with a "925 Sterling Silver Snake Chain Necklace" that is 18 inches long. Agates are formations made of Chalcedony and Quartz, commonly sporting layers of varying colors across their formations. These result from Silica-rich groundwater seeping into the cavities in igneous volcanic rock, transporting minerals that harden in layers over many years. The unpredictable nature of how these stones are formed creates concentric banding and color unique to each deposit, adding a ‘personal’ characteristic to jewelry. Pink Agates can improve concentration, mental function, insight, awareness, and analytical abilities. Pink Agates are known to aid one in overcoming heart bitterness and stabilizing the aura. They're also calming and soothing, dismissing fear and instilling positive energy, courage, and strength, restoring or boosting self-confidence.
