They are not lab-grown or reconstituted. For natural quartz, it is inevitable to have inclusions, veils. Vogel crystals are quartz crystals that are carefully cut in conformance to the findings and teachings of marcel vogel (1917-1991). They are healing crystals and meditation crystals that are cut to maximize the collection, amplification, and transmission of the universal life force.Basically a vogel crystal is cut to amplify, coalesce, and focus thoughts and energy that you wish to direct into your body/mind or that of another person. The design of the crystal allows for your thoughts and energy (and the pervasive universal life force), to enter the crystal at the receptive end, be amplified and focused as it travels in a circular pattern through the crystal, and be transmitted like a laser beam from the focal end. This item is made of quartz crystal.
