A very nice specimen of Lepidolite which displays a natural botryoidal formation, also known as a bubble formation.
Lepidolite is a lithium-rich mica known for its pink and lilac colors. It is a common matrix mineral to Tourmaline and Quartz, providing them with a very aesthetic and glittery base. Lepidolite is mined as a source of the element lithium. Fine-grained masses are sometimes polished into ornaments such as eggs and animal carvings.
