They are in black tektites string together in an elastic bracelet and originate from China. They are also called Tibetan Tektite. And China has heaps in its fields from the meteorite going over and only recently China bringing them to the market so the price is really good.
Unlike Libyan Tektites which have been mined since Ancient Egypt! Stolen from a meteorite website: “Chinese tektites are part of the Indochinite strewnfield. The Indochinite strewnfield of tektites covers a large area of the Earth’s surface. A portion of the strewnfield is found in southeastern China and some of the Chinese islands. The tektites found in this region are black like all others of the Indochinite family….
All the classic splash form shapes are represented in the Chinese tektites including large well-formed dumbbells and teardrops and flat patty shaped individuals. Large pieces of flat or slightly curved sheet like forms not as well represented in other areas of the strewnfield are found from this region. These are often thin in spots and show well the yellow brown color of Indochinite glass not seen in thick complete specimens.”
Energetically I have intuited Chinese tektite bracelets or black tektite bracelets for people expanding their energy but needing support through a greater opening of their Earth Star Chakra to do so. They also want to work on a surprisingly large number of my chakras. Dimensions are for the packaging. Use photos as a guide.
