These 123 Tubular Rutilated Quartz Beads are composed of a clear to pale gray crystal quartz with needle-like rutile crystal inclusions. The majority of the inclusions are black, but some beads also have green, red and/or brown crystals. Rutile is a mineral that is made from titanium dioxide. It is very refractive so, when it is found in quartz, it appears as hairs of colors (gold, red, brown or gray). The variety of the size and shape of the inclusions makes this a uniquely beautiful gemstone. They measure between 12mm and 16mm long and about 4 to 5 mm wide and are not perfectly cylindrical in shape. The hole runs lengthwise and appears to be between 1 and 2 mm in diameter. In the world of crystal healing, rutilated quartz is used to encourage spiritual growth, cleanse the aura, keep away the negative thoughts of others, and works as an antidepressant. It is also said to heal conditions such as impotence, infertility, bronchitis and thyroid imbalances. Country of origin and age are unknown. These 123 Tubular Rutilated Quartz Beads are in very good condition. They had one previous owner who appears never to have used them.
