Gamblers Jewels (Andreas Zidek) / Jennifer Kellogg

Today is lucky 7/7 — and I bet the Vegas slot machines are extra busy. If you're looking for that winning advantage, try boosting your luck by donning one of these casino-themed pieces from Gamblers Jewels. Who knows? The one-armed bandit just might reward you for your style. (The collection is by Germany's Andreas Zidek, whom I also wrote about a couple of years ago.)

Bonus link: for a more subtle "bar" ring, try this band from Brooklyn's Jennifer Kellogg. Also shown are the "casino" bracelets.

Even more jewellery:

• Mimco (Australia) - glam bangles


• Leticia Costa (Brazil) - silver & beads


• Ulrike Zöllner-Krumme (Germany) - brushed gold
