infinity necklace

Most infinity necklaces are made from 925 sterling silver. Some listings describe pieces as 18K white-gold filled over sterling silver. Stones are commonly 5A-grade cubic zirconia. Many items are also marketed as nickel- and lead-free and with hypoallergenic or tarnish-resistant finishes.

Chain lengths vary by listing. Examples include 16 inches, about 17.7 inches with roughly a 2-inch adjustment, and 18 inches—so many options include short and slightly adjustable lengths.

Common closures shown include lobster claw clasps and spring-ring clasps. Some listings also show clip-on styles.

Finishes include 18K white-gold filled and white-gold plating over sterling silver. Several listings note that the chain, pendant, and clasp are plated in high-quality white gold.

Many infinity necklaces are offered as a 12-month birthstone series, with a colored gemstone for each month. Examples provided in listings include April (diamond), March (aquamarine), May (emerald), and June (alexandrite).

Many listings arrive gift-ready and commonly include a gift box (often a pretty white box) with the necklace included in the package.
