There are approximately 27,000 specimens of rocks, minerals and fossils in the Leeds collections. This includes a wide range of material from around the world, including some rare and interesting specimens.

Many of the best specimens were obtained in the nineteenth century by members of the Leeds Philosophical and Literary Society, or were donated to the society by prominent scientists and collectors of the time.​
