Hematine (also magnetic hematite, hemalyke or hemalike) is an artificial magnetic material.^[1] Hematine is widely used in jewelry.^{[citation needed]}

Although it is claimed by many that it is made from ground hematite or iron oxide mixed with a resin, analysis (of one object) has demonstrated it to be an entirely artificial compound, a barium-strontium ferrite.^[2]
