Spring ring clasps are a lightweight type of closure and great for keeping both weight and cost down (on solid gold chains especially). Most people find that lobster claw closures are much easier to close but with it may come a higher price tag in gold due to the heavier weight. 

The most common casual chain style for pendants is a cable chain which are lighter in weight, versatile and easiest to repair. 

Box and snake chains both provide a more smooth surface area to shine giving off a fancier, more evening-like look.

Rope and Spiga (wheat) chains are made with more links that are woven tighter together and are a great choice for heavier pendants. 

For most pendants, 1–1.3mm is an ideal chain thickness, offering an attractive balance of strength and appearance. Very delicate chains under 1mm are best suited to lightweight pendants.

Larger pendants (approximately 38mm / 1.5 inches or longer) generally look best on chains 1.3mm or thicker. Always verify that the pendant's bail opening is large enough to accommodate your chosen chain.

Necklace placement varies depending on neck size, body type, and pendant weight. The illustrations above are intended as a general guide.

Women's most popular necklace length is 18 inches, while 20–24 inches are the most common choices for men.

Children's necklaces are typically available in 14–16 inch lengths, depending on age and size.

When selecting a chain, consider:

Pendant size and weight

Bail opening

Desired necklace length

Chain thickness

Personal style

A properly matched chain should comfortably support your pendant while complementing its overall appearance.
