The Artist I buy from uses Sterling Silver on all Jewelry. Larimar cools tempers and calms fears, relieves stress and nurtures the physical and emotional bodies. It is powerful in meditation and is particularly helpful in releasing emotional bonds, patterns, or principles that no longer serve the highest good. Also known as “Atlantis stone & Mermaid stone” it is said to be finely tuned to the human body particularly the throat area. It increases speech and communication skills and supports the body’s natural healing process. You will receive one randomely pulled bracelet from stock. Sizes are approximately 7 & 3/16 inches long.
