tennis necklace

Tennis necklaces use both simulated and natural stones. Common simulated stones include cubic zirconia and rhinestones. Natural and treated gemstones found in listings include amethyst, citrine, garnet, iolite, peridot, rhodolite garnet, and topaz. Some designs combine multiple gems in multi‑stone arrangements.

Common closures include lobster‑claw clasps and various box‑style clasps. Some sterling or higher‑end listings specify a box clasp with double safety latches, while others describe box‑with‑tongue or standard clasps.

Many tennis necklaces include extenders to adjust length. Examples from listings include an 18" chain with an extender to 20", a model with a 2" extender on a 13" base, and a design listing a 12.6" chain with a 6" extender. Exact adjustment varies by model, so check the item's length and extender specs.

Common lengths include 16 inches and 18 inches, and many pieces add an extender (for example, an 18" necklace that adjusts to 20"). Some listings show longer single lengths (for example 30") or layered combinations such as 16"+18" or 18"+20".

Materials range from metals like stainless steel and sterling silver to plated finishes used in fashion pieces (including 14K‑plated brass). Some items use zinc or other alloy metals in plated or fashion styles.

Closures vary by design and include box clasps (some with double safety latches), box‑with‑tongue style clasps, lobster‑claw clasps, and other standard clasp types. Specific security features depend on the listing and material.
