HEALING PROPERTIES -- This stone is known for: Emotional Balance Physical Well-being Communication These stone tile beads work great with your other TILA beads, as they are the same measurements. HALF: 5x2.5mm - approximately 125-130 tiles in 1 strand The hole measures approximately 0.8mm, and we recommend 0.5mm elastic cord (which we carry) PLEASE NOTE - We give you an approximate number of tiles per strand so you can calculate how many you need for your project. We weigh the beads when packaging for shipments, we do not count them individually. The number of pieces is simply an estimate and nicety for our customers to help determine what is needed for a project. We will not entertain refunds based on an expectation that we did not send enough pieces of beads in a shipment. *DISCLAIMER* - Due to the natural cutting process of stone beads, some strands may include minor variations such as small chips or irregular edges.
