Secret Gem

Secret Gem (秘められし原石) is a material available in Kingdom Hearts Birth by Sleep. It can be used during Command Meld to raise the synthesized command to its max level.

Design
Secret Gem is represented by four jewels with a unique structure. The main jewel is the largest, is tube-shaped, and has facet cuts. Two medium-sized jewels are hook-shaped and revolve around the main jewel. The smallest jewel floats between the two hook-shaped ones. All four jewels are golden yellow with green tints at the edges, and the largest one has a swirling, purple and yellow, smoky design in its center.

An ore is a type of rock that contains important minerals, such as metals. "Secret" may reference the fact that the material can only be obtained through rare drops from the Flood, defeating Vanitas Remnant, or excelling in certain mini-games.
