Chains commonly range from about 16 inches up to 20 inches, and many necklaces include short extenders (often 2" or 2.5") to allow for adjustment.
The most common closures are lobster-claw clasps and spring-ring clasps.
Common citrine cuts and shapes include round, marquise, pear, oval, square and heart shapes.
Common settings include bezel settings and prong-style settings (for example, 3-prong and other prong variations).
Care guidance varies by listing: some recommend professional cleaning, others suggest jewelry cleaners or gentle spot/wipe cleaning, and a few listings do not provide instructions. Check the specific product details for the maker’s recommended care.
