These base-metal beads are made in India, and many are hand-turned (sometimes called "machined"). The majority of them are brass-based, and fairly solid: a bit heavier than most metal beads of similar sizes. We buy these in small batches when we find them; they are not always available. These metal beads are nearly always satin-finished (a brushed or matte finish). Also, they have relatively large hole sizes, so fit larger cord than you might expect from looking at the bead. Use the "Add to Compare" feature to quickly compare hole sizes without having to click into each item. With their weight, and the fact that they aren't as shiny as many other beads, they are excellent spacers for men's jewelry.
