Industry Insight
The lobster clasp takes its common name from the visual similarity between its oblong body and hinged gate, and the pincer claw of a lobster. The formal term in the trade is 'trigger clasp' or 'parrot clasp' in some markets, but lobster clasp is the dominant consumer-facing name in North American fine jewelry retail.
