Why a ladybug means luck
Across most of Europe, a ladybug landing on you is considered a small piece of good fortune, and the number of spots is said to tell you how long it lasts. It's one of the few luck symbols that's genuinely cheerful rather than superstitious — which is why it works as a gift for an exam, a driving test, a new job, or someone who's just had a rough run.
The coin design
The ladybug is set into the coin face rather than sitting proud of it, so nothing catches on pockets, gloves or hair. On a ring that matters more than on a necklace — hands take more contact than anything else you wear.
Why it lasts
Stainless steel beneath the gold plating. It won't tarnish, so a good luck charm doesn't stop looking lucky after a month.
