Sphene does possess a hardness of 5 - 5.5 on the Mohs scale, as such would be recommended for use in a pendant or brooch. Special care should also be taken when cleaning a Sphene, since household dust contains quartz which has a hardness of 7, will scratch and abrade the surface of the stone. It should be cleaned with soapy water and a soft cloth, rinsing well to remove the soap residue. Do not expose stone to harsh chemicals or cleaners. When storing in a jewelry box, wrap in a soft cloth preventing the stone from contact with other harder stones. This stone should not be cleaned in an ultrasonic cleaner or be subjected to steam cleaning.
