Lemurian are a specific type of crystal that is believed to have originated in the ancient civilization of Lemuria, a hypothetical lost continent that some people believe existed before Atlantis. These crystals are identified by their unique appearance, which features horizontal striations or lines on one or more of their faces.

According to belief, these lines are said to represent encoded messages from the ancient Lemurian civilization, which are accessible to those who work with the crystal in a meditative or spiritual context. It is believed that the energy of these crystals can help to activate and stimulate the higher chakras, enhancing spiritual awareness and facilitating access to higher realms of consciousness. 

The record-keepers are typically formed when mineral-rich solution flowed over protrusions on the surface of the crystal point.  They are normally found on only a few of the crystal faces (not all) and they show the direction of the fluid flow as the geologic event that formed them was occurring

Lemurian record keeper crystals are highly prized by those who work with crystals for their unique energy and their potential to facilitate spiritual growth and awakening. They are often used in meditation, energy healing, and other spiritual practices, and are valued for their ability to help individuals connect with their higher selves and access deeper levels of wisdom and knowledge.
