It was 35 years ago that Robert Tateossian, a Wharton School of Finance-educated financier who worked in both New York and London, decided there was more to life than just crunching numbers. So in London in 1990, he established Tateossian Ltd., a line of jewelry that offered distinct and innovative designs made from unconventional materials such as dinosaur bones, meteorites and marine fossils.

Over the past 35 years, Tateossian has become known for his cuff links, but the brand also offers a wide range of men’s, women’s and unisex accessories including bracelets, necklaces, earrings, rings, watches and money clips.

During the Chicago show, the brand will host an event at the British Consul General’s residence to celebrate the milestone anniversary. In addition to the party, Tateossian will be showing what he described as “one-of-a-kind pieces for our 35th anniversary, stones no one has ever seen before. It’ll be really special.”

That will include the Trinity Knot and Quad Knot cuff links, which were designed to speak to the eternal cycle of life across ancient Roman, Egyptian, Islamic and Celtic cultures with their intertwined Triskelion and Solomon’s Knot symbols. There are also the Mobius strip cuff links crafted from all-silver or interwoven yellow-gold, rhodium and black ruthenium or semiprecious chrysocolla or spiny oyster.

The same spiny oyster will be used for bracelets, and there’s a Marine Link necklace inspired by the mariner link chain used to anchor ships.

“They’re ‘wow’ pieces,” he said. “All limited edition and available to our super customers.”

Tateossian said another special piece that will be offered at the Chicago show are the Septa Gear cuff links, which feature seven interlocking gears. “We were asked how we could fiddle with the cuff links to have gears that rotate,” he said. “It took one and a half years to develop and it’s now one of our star products.”

There are also Bryozoan Pebble cuff links featuring oval fossilized stones of bryozoan coral as well as the Red Horn Coral Jasper model crafted from ancient horn coral fossilized and transformed into red jasper.

Dinosaur bones, sourced from Utah, are used to create cuff links and bracelets that offer a natural mosaic, and Tateossian also created a special 35th anniversary platinum cuff link assortment made with rutilated quartz, leopard opal, sky plume agate or dendritic agate.

He said he finds these unusual materials through dealers around the world at gem and jewelry shows who know he buys “weird things. It’s easy to offer an onyx cuff link, but they know I’m always on the lookout for the unknown and unseen.”

At the show, Tateossian’s co-branded collection with Lamborghini will also be on display, including a new line of bracelets.

And building on the marine theme, there will be a Feng Shui Fish pendant in either silver or yellow gold that includes a blue enamel evil eye. “Anytime we do an evil eye, it’s a huge hit,” he said.

Although cuff links and bracelets remain his primary business, Tateossian said he’s seen an uptick in interest in pins and broaches following events such as the Met Gala.

Studs for formal occasions continue to represent strong sales, but those are “geographical,” and only popular in America, not Europe.

Tateossian said over the past 10 to 15 years he has seen a “dramatic change in the way men wear jewelry. There is no hesitation anymore.” So it’s become commonplace to see guys sporting a stack of bracelets or even their grandmother’s strand of pearls or a diamond tennis bracelet.

“The barriers are broken down as men become more confident in their masculinity,” he said.
