This is an extra-large natural nugget turquoise bead, suitable for leather cords from Goros, etc. The hole diameter fits thick cords, making it easy to match with bags, etc. As you can see, this is a high-grade turquoise, unlike commercially available turquoise. Origin: Kingman Mine, USA. There are no cracks. Thank you. We apologize, but this is a limited quantity, and this is all that is currently available. The next restock is undecided. We were finally able to procure these, but the price has increased due to the weak yen. Thank you for your understanding. We do not plan to offer beads of this size in the future. Nugget bead size: Approximately 2.8cm long, 1.6-2cm thick, hole diameter 3.5mm
