Black Onyx and White Howlite Necklace, 23", Turquoise Mustang

Turquoise Mustang designed this 23-inch necklace combining 8mm black onyx and white howlite beads. Howlite is a calcium borosilicate hydroxide mineral that is opaque white with grey veining — it is sometimes dyed to imitate turquoise but is here used in its natural white state as a color contrast to black onyx. Available exclusively through Turquoise Mustang.
