Custom motorcycle club rings
Need more than a retail ring? We also create custom motorcycle club rings for MCs, riding groups and event chapters. A custom project can incorporate your approved club name, initials, emblem concept, anniversary year or officer role, with coordinated sizing for individual members. Our team can help plan a consistent club ring order while keeping the final artwork practical for silver casting and long-term wear.
Care
Wipe with a soft silver-polishing cloth after wear and store dry. Remove before swimming, harsh chemicals or abrasive work. Oxidized recesses are intentional; avoid aggressive polishing inside dark details.
