fake gems

Common materials for decorative fake gems and craft beads include glass, acrylic, PET (polyethylene terephthalate), and other plastics.

Many flat-back acrylic gems are glued onto paper, fabric, or plastic. Some glass rhinestones are sew-on with holes for needle-and-thread, and other stones use metal bottom claws or mounts for secure attachment.

Common uses include event and holiday decorations, jewelry and beading (necklaces, bracelets, earrings), and kids’ crafts like key chains and mobiles.

Store acrylic flat-back gems in a cool, dry place to help prevent discoloration.

Sew-on glass rhinestones include holes in the base for needle-and-thread attachment. Other options come with metal bottom claws or mounts to hold stones securely and improve wear resistance.

Pony beads are commonly listed as about 8.5 × 6 mm with a hole diameter around 3.7 mm; letter beads are shown as about 6 × 6 × 6 mm with a hole diameter near 3.2 mm.
