Metal beads and discs are common—typically brass, copper, or stainless steel. Many listings note an 18K gold‑plated finish, and some specify medical‑grade 316L stainless steel for hypoallergenic properties.
Typical chain lengths include 6" (often sold in sets), a 6"+2" adjustable option, and about 6.5" for elastic styles. Charm sizes mentioned include a 9×9 mm letter medallion and an 8×8 mm heart.
You’ll find lobster‑claw clasps on adjustable chains and stretch/elastic band designs that slip on without a clasp. Stretch pieces commonly use elastic thread or cord for easy on/off wear.
Most are described as gold‑plated, with many listings specifying 18K gold plating or an '18K' coating; some descriptions note multi‑layer plating techniques.
Age recommendations vary by listing—some target adults (18+), while others list younger recommendations such as 14+ or 15+, depending on design and size.
In addition to letter medallions, bracelets often use polished metal beads and accents like heart pendants, small crosses, pearls, and glass beads.
