The 16/18/20/22/24/26 inch size range makes it easy to layer with other chains for a personalized layered look.

Buying Guide: What To Consider When Choosing 18 Inch Chains
- Material and skin compatibility: Choose hypoallergenic metals (stainless steel, sterling silver, gold plating) if you have sensitive skin or allergies.
- Width and weight: 0.8mm to 0.35mm widths offer different silhouettes. Thinner chains are delicate-looking but may be more prone to snagging; thicker chains are sturdier but heavier.
- Clasp type and durability: Lobster clasps tend to be more secure than standard spring clasps; ensure the clasp matches your wear style and daily activity.
- Length options and adjustability: An 18 inch length is collarbone-friendly for most; extensions help accommodate pendants and layering preferences.
- Metal care and maintenance: Gold-plated or silver-plated chains require occasional cleaning to preserve luster and resist tarnish or wear on plating.
- Versatility for layering: If you plan to layer, consider pieces with varying lengths or textures to create depth without clashes.
