In case the Playmobil model isn't enough to hook you, let me explain what it is, exactly, that you're looking at: Toblerone rings. Toblerone, people! Alongside cheese and pizza, part of the trifecta of wedge-shaped foods! (Cake, of course, being disqualified due to the threat of coconut.) More fun below, including the "rock star" ring with nostalgic cassette; all pieces available from Singapore's Carnival Shop.
Bonus link: if you grew up with the Slinky instead of with Playmobil, you might appreciate Tel Aviv jeweller Gal Barash and his industrial designs, including a series based on the classic toy.
It is, last I checked, 2009. Yesterday's flower child is now in her 60s. Are we not yet at a point in time where we can kill the phrase, "not your grandmother's pearls"? Because I think these could be your grandmother's pearls, especially if your grandmother has a birthday coming up.
Above: German jeweller Verena Klette of Renitent keeps her pearl rings light but sturdy with the use of capped wire.
Pink pearls and eroded bands from Sweden's Anna Martinsson.
Pearls and matte silver from Germany's Andrea Fielitz.
A burst of pearls from Massachusetts' Andrea Zatarai, whose one-of-a-kind pendants should not be missed!
Bonus link: check out Verena Klette's other project, Ringen, where you can "spin the wheel" on each of the four "quadrants" of a ring and get a random design combination, which she'll custom make for you.
From square mood rings to the Three Little Pigs' houses in three different metals, French jeweller Catherine Abrial offers up a trove of charming treasures.
Another French jeweller with square face rings  albeit of an entirely different kind  is Cendrillon, who works in polymer clay.
Every time I get on my treadmill, I feel like I'm performing some kind of hackneyed paean to the modern rat race. Capturing that feeling in exquisite, non-hackneyed ring form are these "bridge" and "crossroads" rings, above, by Germany's Dieter Dill Design. Scale the image down to size in your mind and think of how tiny those people must really be!
Here are some more "bridge" rings (minus the drudging herd) by New Mexico goldsmith G. Phil Poirier.
What do accordions, honeycombs, boxes, flutes and 18th century French painter Jean-Antoine Watteau have in common? They all have pleats named after them! Luckily, you don't have to be able to differentiate them in order to enjoy them. Rings with pleats (and other shapes) from Argentina's Luz Arias, above, and Spain's Núria Farré Pàmpols, below.
If you prefer a simple, minimal fold, check out Australia's Emma Kidson and her origami box rings.
White and chocolate porcelain get all dressed up with just the right amounts of silver and gold. Rings by Spain's Pilar Cotter.
For more porcelain, check out the aptly-named "cumulus" ring by German jeweller Theresia Konrad.
From the junk drawer to your accessories drawer: ribbon rings (above) and rubber band rings (below) from Germany's Johanna Bauer and Lena Hülsmeier, respectively.
Bonus link: if you think of rubber bands more as weapons than accessories, this ring sight can help you improve your aim. From UK designer Stuart Bannocks of As Well As Design.
Coffee, shoes and books: for some, the holy trinity. For Japan's au lait, the inspiration for their "milk" collection, an adorable line of gold and silver jewellery featuring the "mushroom hair" girls.
Bonus link: speaking of coffee, it's all about the vaunted bean at Germany's Bohnjuwelen, a coffee-themed collection from last month's Sonja Pfingst Bischof.
There's something vaguely macabre about having a cow at rest inside a piece of what I presume is cow-bone. But the ring is named "Cow Enjoys the View" so, if the cow's cool with it, moo on. More from German jeweller Ricarda Enderweit below; as always, visit her site to view the rest!
Lots of bone (sans cow), horn and gold at the Shompole Collection, where you'll find jewellery and housewares made by African artisans.
The word "clusters" always makes me want to eat cereal. Well, I'd better get my bowl and spoon because here are some clusters in assorted shapes and metals. First up: gorgeous blue enamel coupled with gold by London-born Jacqueline Ryan, who now makes her home in Italy.
Bonus link: more clusters! This ring is a cluster of pods, each set with a different colour gemstone. By German jeweller Gitta Pielcke (who has a thing for frogs and turtles).
Bonus link: here's a ring that more obviously owes its shape to a car. This 1967 VW Luv Bug is just one of many models available from California's Hi Octane.
These jewellery objects may not have been specifically designed to be rings but I'm going to take the liberty of saying they could be rings. (It might help if you squint and tilt your head a bit.) Any excuse to post these amazing creations in glass, sand, clay, iron, silver, seaweed and more by Spanish-born, Amsterdam-based Estela Saez Vilanova.
Another piece that originates in part from the sea is this fossilized sand dollar ring from Chicago's Dollybird Design (US$225).
I have to confess I'm not big on inspirational phrases (unless it's a chant of "go, Canucks, go!"). All that hoping and dreaming and flying and dancing and wishing and laughing? Exhausting. This inscription, though, with its simple statement of fact, hits the right note for me. Ring from the "messages" series by Belgian jeweller Anne Zellien.
If you prefer a more abstract message, try the "etc" ring by Amélie Blaise. The Paris designer uses her own photography in her jewellery, most often drawing on images of birds, flowers, other plantlife... etc. As it were.
Bonus link: it's tough to see here but the removable top on this ring reveals the phrase, "force de ma vie." By Swiss jeweller Mireille Lalive d'Epinay of Mir Design.
Leaves made of wood are like... um... fingernails made of arms? I got nothing. What I do got is this stylized, sprouting "bloom" ring by Michigan's Rosemary Lynn Mifsud, whose "seed" collection uses silver and recycled post-industrial wood.
Above, more wood and silver (in 98% and 2% proportions, respectively, according to the "nutrition facts") from Food, an eco-conscious jewellery line by Toronto's Metsa Design.
Want even more wood and silver? Check out another Toronto jeweller, Jenny Greco, for lots of chunky, modern pieces.
This post contains both natural and artificial colouring. Pastel gemstone clusters from California's Mali Sabatasso, above, and bright acrylic from Chile's Biomo, below.
Want natural and artificial in the same ring? Paris jeweller Laurent Guillot combines clear acrylic with metal and stones (pictured is his pyrite ring).
All rings above by Colombia's Mariana Shuk  visit her site for lots more!
The ring above is a tube with bundles of silver; the ring to the left is a bundle of silver tubes! By Florida metalsmith Cyndie Smith.
Delphine Jaulhac followed in her father's footsteps... and then veered a little to the left. While her dad was an ivory sculptor, Delphine creates jewellery using ivory of a different kind: tagua, aka vegetable ivory. See all the gorgeous pieces on her site, Epiderme Sur Epiderme.
Bonus link: for a bit of real ivory (recycled, of course), check out this "key ring" in recycled piano key ivory and sterling silver by North Carolina's Ashley Brodie, US$85.
Another wide-span wing ring, this time in recycled silver, by London jeweller Andrew English.
Bonus link: here's another ring that's a long, continuous strip of silver (200mm, in this case). Unfurled, it reveals a set of coordinates to a personal place. By Dutch artist Wieki Somers.
* As I wrote this post, it occured to me that perhaps tapping the pocket caused the cookies to break into pieces, so that they were increasing in number only from a child's perspective. But I seem to recall that the cassette of songs came with a picture book and that the cookies were shown to really be multiplying in magical fashion. And that concludes this edition of the Overthinkers Anonymous Newsletter.
We go from rings topped with rings to this ring topped with a key. Magnetic hollow ring by Emily Rothschild of Cambridge, MA.

While spring may have officially sprung last month, April didn't arrive until today  and it's really this month that says "spring" to me. Maybe because they both contain the letters p-r-i. Of course, spring also contains the letters r-i-n-g. You know what else is spring-y and ring-y? Wing-y creatures perched on branches. Above: butterfly ring by Jenni Caldwell, a Scottish metalsmith in Sweden, and "finch & branch" ring by New York sculptor Perry Gargano.
Here's one more bird-on-a-branch ring. This silver piece is by North Carolina jeweller Amy Moore, aka Honeybee.
