Common chain lengths run from adjustable 16–18 inches up to 24 inches. Typical examples include 18-, 20- and 24-inch chains, and at least one listing adds a 2-inch extension for extra flexibility.
Pendants range from about 11 × 22 mm up to about 32 × 60 mm, with other common sizes shown such as 23 × 38 mm and 22 × 16 mm.
Many listings indicate the necklace arrives in a gift box—often a branded or black gift box—so they are ready for gift giving.
Common materials include sterling silver (often rhodium-plated), stainless steel, and pieces with gold-plated accents — for example listings described as 14K gold over sterling silver.
Finishes include rhodium plating on sterling silver, gold plating such as 14K or 18K over sterling silver, and two-tone black & gold IP plating on stainless steel. Some listings note combinations of rhodium and 18K gold accents.
Some listings include small natural diamonds—for example a 0.003‑carat natural diamond (I2 clarity, H–I color) and a 0.02‑carat diamond (G–H color, I1–I2 clarity).
Care instructions vary by material: many listings recommend wiping with a polish cloth; some sterling silver pieces advise using jewelry cleaners; and a few items note tarnish-resistant or rhodium-plated finishes that reduce tarnishing.
Chain widths range from very thin (around 1 mm) through mid widths (about 2.5–3 mm) to chunkier styles near 6 mm and some pieces around 10 mm (approximately 3/8 inch).
