Birthstones are members-only den items that were introduced to Animal Jam at the beginning of 2013. They are sold at Epic Wonders.
Birthstones vary in appearance. The particular gem of the month is inlaid in a gold-like metal. Each of the twelve birthstones (for twelve months) is unique. They also sparkle. They are all rather small.
- The stone of the month comes out on the first of that month and leaves at the end of the month.
- There is a birthstone display where Jammers can place their birthstones.
