Beads, 12mm Round Tibetan Blue with Black Matrix on extender Sterling 17-19"
The mine where a piece of turquoise was found—not its color, nor its matrix, which refers to the veins and patterns of the stone—is the primary factor in determining its value. Historically speaking, the finest turquoise came from the mountains of Asia. In the 20th century, however, the copper-rich American Southwest supplanted them as the primary source of rare, and valuable, specimens, including collector favorites such as Bisbee, Lander Blue, and Number 8 (Black Web). Tibetan Turquoise is highly prized. Hubei also has some of the most beautiful natural Turquoise.
The large size of these beads makes them really hard to find. Turquoise is becoming so rare that large beads are not being made. Too much waste. I have had these beads since the 1980's. They are truly one-of-a-kind.
