This appears to be a dark, textured crystal-studded mesh bracelet featuring a polished silver-tone magnetic clasp.

If the bracelet has no maker's marks or metal hallmarks (such as "925" for sterling silver) on the clasp or inner surface, it is considered costume jewelry.

Without precious metals or a designer brand name, its retail value typically ranges from $5.00 to $15.00. Visually identical hematite rhinestone and mesh magnetic bracelets are commonly sold by fashion retailers like Deb's Jewelry Shop or marketplaces like Etsy within this budget price tier.
