Thank you for viewing! This is a bracelet made with Lepidolite Silica (Scaly Mica, Quartz), Zebra Jasper, Howlite, and Chalcedony. Lepidolite is also known as Scaly Mica in Japanese, and is characterized by its shimmering, fish-scale-like appearance. It is mixed with white silica (quartz). It's a beautiful natural stone with a scale-like shimmer within the marble pattern. Howlite is also known as magnesite and is characterized by its gray patterns. Jasper is an opaque natural stone, characterized by various patterns depending on its composition. Zebra Jasper in black tones is selected and used, and because it is round-cut, it has a slight shine. Chalcedony refers to the transparent stones among the chalcedony family. For the chalcedony, we use stones with 2mm holes to accommodate the rubber knot. Comes with an organza pouch. Materials: ♦︎ Lepidolite Silica 8mm ♦︎ Howlite 8mm ♦︎ Zebra Jasper (black) round cut 6mm ♦︎ White Chalcedony 2mm hole (for rubber knot) 8mm ♦︎ Brass crystal glass rondelle 6mm ♦︎ Elastic fiber polyurethane rubber, quadruple strand Bracelet Size: Inner diameter approximately 15mm The rubber is passed through the loop and tied twice, then crossed and tied twice more. No adhesive is used on the knots. Therefore, the knots may come loose during use. If this happens, please gently pull on the knot. Please note that there may be possibilities of rust or discoloration, and color unevenness due to the natural stones. Material: Natural Stone
