This is an Itoigawa jade bracelet. It's a genuine Itoigawa jade bracelet purchased from the online shop "Kino Sei." It's said to be from the Aomi River system, with colors ranging from pale white to light blue, light green, and pale lavender. I was drawn to the variety of colors and bought it, but I mostly use another jade piece from the same shop, so I'm putting this one up for sale. It's only been tried on, so I think you'll be able to use it comfortably. The inner diameter is just over 15cm (8mm x 22 beads). 8mm Aomi River system jade bead bracelet. - Material: Aomi River system jade - Size: 8mm - Colors: Pale white to light blue, light green, and pale lavender - Design: Bead bracelet Thank you for viewing.
