Such designs have earned a place in showcases and hearts, but their longevity can make them look dated. There's a way to have your classic and look current: mix the much-seen with something more unusual. (All prices in $US unless noted.)
Punching up Pandora
Pandora or similar charm bracelets are busy pieces, so I would tweak them with clean, geometric design, and if it wouldn't break hearts, swap out the more jeune-fille charms like the little girl or teddy bear.
Budget zhuzh: Jane Diaz' "diamond" pendant; gold-plated brass on a black silk cord. Price, $88.
A Modernist Bernard Chaudron bronze and enamel pendant has the fluidity and texture for the nuggety charms, and you are not going to find this in a mall window! Price, $CDN 130 from Samantha Howard.
Balance for bangles
A 46-carat ring of green pryhenite stands up to the stack. This example is from EdwardOwl; price, about $290.
For those who thrilled by colour, Murano glass rings are marvelous buys. I especially like this sleek slice of blues with gold leaf—and the price: about $35! From MysteryofVenice.
I'd wear it with a Late Victorian (ca. 1880) silver and rose gold bracelet; price $1, 200 from Isadoras Antique Jewelry.
Another way to wear a classic modern ring: add unusual Edwardian earrings, but that might be a bigger spend. Warned you, now here they are: moonstones and diamonds set in silver and gold; price, $2, 775.
Tennis: Play mixed doubles
If you're up for a cheeky twist, try this Hermès penguin bangle, about $450:
A woman in my building pairs a formidable one with Swarovski's Stardust double bracelet; price, $79. I like the edge of hers in grey, but it also comes in eighteen colours!
When I think of taking on Yurman-type cable bracelets, floating heart pendants, or 1980s gold 'power' necklaces, my wrists go weak. They had their moment, but, like '70s padded-shoulder jackets, there is no plausible companion piece that extends their lifespan. Perhaps they could be worn ironically by a girl with very short bangs and a leather kilt.
If you have good materials, repurpose them in a new design.
Reader Kirsten Giving recently showed me a graceful piece made by Montréal jeweller Janis Kerman, using a client's material. Ideal way to recycle gold, and neither the petal pearl nor the small smokey quartz round are costly.
Made me wish I had something that's past its time. Sometimes you find the jeweler, than sift down to the bottom of your box for some unworn items!
