There's a neat treasury on Etsy of items made by New England artists and crafters. One of my malas is featured (the one I have pictured here). It's made of nephrite jade, Czech glass, sterling silver, cotton thread, and a Tibetan white turquoise guru bead.
Every mala I make is designed with a distinct meaning and purpose. It's important to feel a connection with the mala you're choosing--that instinctual, visceral "ah" feeling that lets you know it was meant for you. If you're in the market for some prayer beads and/or malas, take some time, look around, and follow your intuition. The most important thing is to feel connected to your mala.
