Thank you for viewing. This is a 7-7.2mm bead bracelet made with Gibeon meteorite. The Gibeon meteorite is an iron meteorite that fell to Earth approximately 4 billion years ago, and its characteristic "Widmanstätten pattern," a beautiful crystalline structure, is its charm. - Popular for warding off evil and negative energy - Unisex size Due to the natural properties, there may be slight scratches or surface irregularities. Please understand this before purchasing. Also, the color may differ slightly depending on your monitor environment. *Returns are not accepted to prevent switching of items. I purchased this from the reliable natural stone & Chinese tea shop, Lin, and have kept it with care. Lin sources and processes authenticated Gibeon meteorites, so you can rest assured. However, as it does not come with an appraisal certificate, I am offering it at a lower price. I replaced the string with a new one for the listing, but please be careful as each bead has weight, and you should take care to prevent the string from breaking and the beads scattering. _(._.)_ Thank you.
