The first cavity is defined by an interior surface of the main body, and is filled with a weighting media to improve stability. The second cavity is defined by an exterior surface of the main body, and holds a capsule configured to contain ashes or mementos. The first cavity and the capsule are sealingly enclosed with a plug and a cap, respectively. The portable tombstone is molded from a polymeric material having a stone-like appearance.
