Cape amethyst beads are formed by layering amethyst with milky quartz to form beautiful patterns in the stones. They also lighten the color of purple, ranging from a purple-tinged white to lavender. Amethyst itself is a variety of quartz crystals that are violet in color. The stones are formed in high heat, often occuring in geodes formed in volcanic rocks.
Semi-precious stone beads are mined all over the world and then are usually cut in China. They will often be dyed or color-treated to enhance their appearance. We select the best quality semi-precious that is available, and try to avoid finishes that are not durable. It is best to assume that some semi-precious beads will fade over time.
