Birthday bracelets are commonly made from brass or an eco-friendly copper base with 18K gold plating. Some listings use 925 sterling silver for a higher-end, tarnish-resistant option.
Common lengths listed are 6 inches, 6.5 inches, and 7 inches. Many bracelets also include extension chains—for example, sizes shown as 6+2.5 inches or 6+2 inches—to provide extra adjustability.
Typical closure types include lobster claw clasps, stretch (elastic) bands, and pull-on (slip-on) styles, depending on the design and level of adjustability.
Care recommendations commonly advise spot-cleaning or wiping the bracelet with a soft cloth. Some listings note a waterproof coating or water resistance for specific beaded stack designs, but care instructions can vary—follow the seller’s notes for that listing.
Most listings state the bracelet includes a gift box; some items are packaged in a gift box or a velvet pouch for presentation.
Adjustability is provided either by extension chains (examples shown as 6+2 or 6+2.5 inches) or by elastic/stretch designs, which are typically listed as about 7 inches for flexible wear.
Many bracelets are described as gold plated—specifically 18K gold plating over brass or copper bases—while some listings note a polished finish on sterling silver pieces.
