Closures reported include spring-ring clasps, lobster-claw clasps, and occasionally clip-on styles.
Listing terms include gold plated, plated in 14K yellow gold, 18kt yellow gold over sterling silver, and 14k gold ion plating over a brass base.
Cable chains are commonly used. Reported chain thicknesses include around 1 mm and about 1.20 mm in the listings reviewed.
Some necklaces include removable charms (examples: bows, dog tags, hearts, envelopes, palm tree charms, pearls), come gift-ready with packaging, or are described as multiple pieces in one because of removable charms.
