This is a magatama (comma-shaped bead) made from Gyoku found at Shichiri-nagahama. It's a type of chalcedony that forms mainly in rhyolite. It's as hard and tough as jade, making it quite unique. Large raw stones are becoming increasingly difficult to find, and this stone is highly valued in Aomori. - Material: Natural stone - Color: Beige - Shape: Magatama - Hole: Yes - Use: For necklaces and pendants Please refer to the calipers for the size. Thank you for viewing.
