This sweet little heart bead has been crafted using an old traditional Lampwork glass technique. This involves heating glass rods to melting point with a hand held torch, and then combining them in an artistic manner. Next the glass is cooled and processed to give it strength. The loop on the top of th bead acts as a bail. Thus, you have your choice of cord, ribbon or chain. It is quite unique . It measures about 3/4 of an inch from the bail to the tip of the heart.Thank you and enjoy my store.
