Silver and glass necklace with a baby marimo moss ball, rare red coral and white sand inside. Glass vial charm measures 1.4" long. 18" long necklace (total length with charm). The vial is sealed securely to create the beautiful eco-system inside, no need for water changes! Moss loves the shade, so indirect or indoor lighting is best - keep away from bright light. When the necklace is not being worn, remember to put it somewhere so it still receives light.
