How do I secure an antique clasp?

Most clasps utilise a traditional box tongue, safety catch, or spring-loaded gate that requires a firm press to release. Check that the internal spring holds tension and that the tongue clicks audibly into place before wearing.

Can these clasps be worn at the front?

Many of these clasps are deliberately designed to be displayed as decorative elements on the chest or collarbone rather than hidden at the nape. Pieces set with diamonds, sapphires, or emeralds were often made to rotate to the front.

What length are these chains usually?

Neck chains and watch chains listed here typically measure between fifteen and eighteen inches, though longuard chains extend further. Shorter lengths sit closely around the neck, while longer variations accommodate pendants and belt buckles.

How do I identify the period of a clasp?

Stylistic cues such as geometric Art Deco lines, Edwardian openwork, or Victorian yellow gold weight point toward specific eras. Hallmarks stamped on the gold components and the cut of any accompanying diamonds also clarify the date of manufacture.
