Lemurian seed crystal is said to be an alternative name but seemingly the two materials are not exactly the same. From what we understand, the main difference relates to the striations on the faces of the crystal.
The striations which can usually be felt as well as seen are what makes lemurian quartz different to other quartz crystals.
Discovered as recently as the early 1990's, lemurian quartz is believed to be associated with the ancient Kingdom of Lemuria. This civilization first mentioned by zoologist Philip Sclater in 1864 was said to have been wiped out by a cataclysmic event. The island of Lemuria subsequently sunk beneath the Pacific Ocean.
The people of Lemuria supposedly predicted the event so prepared the seed crystals to preserve their knowledge and traditions.
Lemurian quartz is highly sought for its metaphysical healing properties. With it being a natural record keeper it can be used to retrieve information about the past.
Although we're interested in the metaphysical healing properties of crystals, our primary interest is more scientific. For this reason when doing research on rocks and minerals in our collection we like to look at both sides of the story. This article by Hibiscus Moon makes interesting reading. This thread from a forum post on Mindat which is a mineralogical reference website takes a different approach but is also well worth reading.
Whatever your reason for being drawn towards rocks and minerals, this beautiful unpolished lemurian quartz crystal certainly won't disappoint.
