An angular, hollow space that resembles a mineral inclusion is referred to as a negative crystal. This term describes a type of inclusion where the space left in the mineral conforms to the shape of the surrounding crystal structure. Negative crystals typically occur in minerals that have grown around or over voids left by other minerals or gases during the crystallization process.

This phenomenon is distinct from the other options. A void simply describes an empty space within a material and doesn't necessarily have a crystalline shape or structure. A bubble typically refers to a small spherical cavity often formed by gases during the cooling or solidification of magma and is not angular in shape. An inclusion is generally used to refer to any material that is contained within another, often affecting the clarity or appearance of gemstones; however, inclusions usually represent foreign materials, rather than a space or hollow area. Hence, a negative crystal specifically denotes an angular, hollow space shaped like a mineral inclusion.
