Howlite Collection

Shop natural howlite gemstones and specimens for jewelry making and collecting. Our howlite collection features white howlite cabochons, tumbled stones, palm stones, and raw howlite nodules sourced primarily from Canada and the United States. Howlite is a calcium borosilicate hydroxide mineral prized for its striking chalk-white color with distinctive grey-to-black web-like matrix veining — a pattern so similar to turquoise that howlite is one of the most commonly dyed gemstones on the market. We disclose treatment and dye status on all listings. Natural white howlite has its own understated elegance and is frequently used as a turquoise or magnesite alternative. With a Mohs hardness of 3.5, howlite is best suited for cabochons, pendants, earrings, and beadwork. Ethically sourced with full origin and treatment disclosure.
