Approximately 2 inches. Druzy is the glittering effect of tiny crystals that have formed over the top of a base mineral. The druzy gems grow slowly over millions of years and are found as the very last layer of growth on agate. Druzy is believed to be associated with peace, tranquillity, patience, intuition, and unconditional love. They amplify the body's natural healing properties and strengthen the spirit. They also provide the balance necessary to avoid depression or unnatural feelings of fear or dread.
