Design a mechanical secret-message pendant inspired by vintage cipher machines and rotating puzzle jewelry. The pendant should be cylindrical or round, with several rotating rings around the body that contain engraved letters. When the rings are rotated and aligned, they can form hidden words or short messages. Design characteristics: • The pendant should have 3–5 rotating letter rings, each engraved with the alphabet A–Z. • The rings should rotate smoothly to allow the wearer to align letters and create words (similar to a simple cipher or puzzle lock). • The letters should be engraved or embossed in a clean serif or minimalist font. • When aligned, the rings can spell meaningful words such as LOVE, SECRET, FOREVER, or custom messages. Structure: • The piece should be a pendant (not a ring) that hangs from a chain. • The body should look like a compact mechanical cylinder or stacked rotating discs. • Include subtle mechanical details like small ridges or grooves on the edges of the rings so they look tactile and easy to rotate. • The end caps of the pendant can have a simple decorative symbol, such as a spiral, sun motif, or minimal engraved pattern. Style: • Keep the design elegant and minimal, not overly complex. • Use rose gold or yellow gold for the main structure. • Optionally add small diamonds or gemstones on the outer edges or end caps for luxury accents. • The overall look should feel like a romantic puzzle pendant or secret message locket. Concept: The pendant represents a hidden message that only the wearer can reveal, combining jewelry with a playful mechanical puzzle. It should feel modern, romantic, and slightly mysterious, inspired by vintage encryption devices but simplified into an elegant piece of jewelry.
