Howlite rates 3.5 on the Mohs hardness scale, softer than many gemstones. It works well for occasional wear but may scratch with heavy daily use. Remove howlite rings during manual tasks.
Natural howlite shows white coloring with gray or black veining in irregular patterns. The veins should look organic rather than uniform. Our howlite stones are genuine and unaltered.
Clean howlite with a soft dry cloth. Avoid water, chemicals, and ultrasonic cleaners since howlite is porous and can absorb liquids. Store separately from harder stones to prevent scratching.
