These necklaces are a wonderful way to represent children's birthstone, or just your own! Up to 8 peas can fit into one Pod. Pendant is made from galvanized steel, so no rusting or allergic reactions occur. All birthstones are available and I can add initials for an extra charge. Chain is sterling silver and 18". Multiple pendants on one necklace is possible, please refer to my other listings. **Please enter months needed in the "notes" section.
