Lemurian Quartz crystal are also known as Lemurian Seed Crystals or Lemurian Star Seeds, mainly found in Diamantina region of Brazil which is where I have sourced them although there have been more pieces being found elsewhere.
They have deep lines on the sides, like a ladder, (Barcode) which is what  identifies them. True Lemurian Quartz crystals have alternating patterns on their shafts. 
They are an important crystal as they are thought to carry messages from the lost continent of Lemuria, it is believed that the information is encoded within its barcode.

Lemurians are also wonderful healing crystals, they are said to be a very high vibrational stone, and are a true energiser stone. 
 they remove karmic hurts from heart, and have a frequency that connects to the crown and soul star chakras, thus making a person soul aware, they also serve as a reminder that whilst we are all individual, we are also very much connected.
