This wonderful starbeing or alien ET crystal skull has been carved from natural mahogany obsidian. Mahogany obsidian is a silica rich volcanic rock containing spotty areas of oxidized magnetite and/or hematite that are coloured deep brick-red/mahogany brown. It is finely carved and polished. Love the starbeing shape - I have many now for myself and have found them to be very much a Starseed's family of skulls. This one gave me the name 'Sentient' for itself as soon as I first held it. There is so much wisdom within Sentient. There is a lot of esoteric knowledge to be gained. You must be patient with Sentient as he does not divulge all his knowledge at once. But you gain more and more as you work with him. He is magnificently beautiful! And he also has a strong connection to Archangel Uriel, and embodies his energies. Sentient measures 5-1/4" long, 4-5/8" tall and 3-3/4" wide. Metaphysically speaking, mahogany obsidian helps remove energy blockages that sap one's inner strength. It is also used for protection and grounding. This obsidian can strengthen the aura, further protecting the person. SHIPPING INCLUDES TRACKING WORLDWIDE.
