Raw Howlite is a white borate mineral marked by grey and black veining that runs through the stone in an irregular web. These unpolished pieces show the characteristic marbled appearance, a chalky white to cream base with darker vein lines tracing across the natural break surfaces. Each stone is left rough apart from light cleaning, so the veining pattern and base color differ from piece to piece.
Howlite Features
- Natural howlite with distinctive grey-black veining
- Chalky white to cream base with marbled patterning
- Raw unpolished pieces retaining natural fracture faces
- Roughly 2 to 3 inches, about 5 oz per piece
- Sold individually as one hand-picked stone
- Matte surface texture rather than glossy
Howlite Benefits
Howlite's white-and-grey veining gives it a marble-like look that fits neutral interiors without competing with other decor. Raw pieces show the vein structure more clearly than tumbled ones, where polishing can flatten the contrast. It is one of the most affordable natural stones available, which makes it practical for filling out a specimen tray, using in a display arrangement, or picking up as a small gift. The size sits well on a shelf or desk without taking over the space.
Howlite Materials
Howlite is a calcium borosilicate hydroxide, first identified in Nova Scotia in 1868. It rates 3.5 on the Mohs hardness scale, making it notably soft and easy to scratch. Its porous white surface takes dye readily, which is why howlite is commonly dyed blue and sold as imitation turquoise. These pieces are undyed and show the natural coloring. Most commercial howlite comes from California and Nova Scotia.
Howlite Usage Tips
- Clean with a soft dry cloth; avoid soaking, since howlite is porous
- Keep away from oils, dyes, and colored liquids that can stain the surface
- Store separately from harder stones, as it scratches easily at 3.5 Mohs
- Display out of prolonged direct sunlight to keep the white from yellowing
- Handle gently, since raw pieces can chip along the vein lines
