The Birthstones Collection is a set of members-only den items that were introduced at the beginning of 2013. The set consists of twelve gemstones that are sold seasonally (one for each month) and a hanging display shelf that is sold year-round 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.
- Although it is not a birthstone, the Birthstone Display was released alongside the birthstones.
