Made in St. Louis: Jeweler’s works are influenced by nature | Lifestyles

Contemporary jeweler and educator Robert Thomas Mullen connected with nature early in life. As a child, he collected stones, shells and rocks on his vacations, recognizing their beauty and husbanding the memories they held.

His jewelry — worked in silver or gold combined with stone, gemstones, shell, fossils, petrified wood and found objects — holds particular interest for people newly aware of the natural world.

The wonder cabinet of RTM • Mullen uses jewelry elements today he may have selected 20 years ago. “I’ve been collecting pieces since I was about 12,” Mullen says. “I have a dresser with each drawer full of stones and things I’ve selected in my travels and on walks. I don’t forget about things. I can go to the right drawer and find the specific piece I’m looking for.”

Friends often bring back odd bits from their travels for Mullen, which he uses in his jewelry. He also casts natural elements for some of his pieces.

Writ in wood • One nontraditional material Mullen likes to use is petrified wood from southern Arkansas, which often has inclusions of crystals that form in the mineralized waters as wood turns to stone. “The wood will have glints from crystals growing in it. The ones I really like have copper or iron deposits, which can cause colorations. They can be brilliant, but you still see the wood patterns,” he says.

Stone Soul • Mullen doesn’t cut stones himself; he buys cut semi-precious gemstones that he pairs in artful asymmetry to create earrings with movement, shape and fire. One dangle earring is not a repeat and reverse of the other in a pair. 

He fabricates a specific setting for each stone in the pieces he makes. He uses bezel wire that makes an open back to keep things lightweight. The open back also allows for more flash in the piece.

Celebrate well • Mullen created a pair of drop earrings with his longtime friend Jessica Douglass of Flowers & Weeds on Cherokee Street to make something special for her wedding. One of the pair of earrings had a yellow crystal; the other was brightly green. They hung from two stones that suggested a butterfly in flight, and form a symbol of hope and growth. “The earrings were perfect for me,” Douglass says. “We have been friends since grade school, high school, plus we were both on the swim team.”

Mullen and Douglass still interact today through his jewelry. She supplies bright bits of dried flower confetti that he captures under crystals to make his flower mosaic jewelry.

Memento mori • The pandemic also moved Mullen to make new pieces for those who grieved.

“During COVID, I started doing memorial pieces for friends, and later for people whose loved ones have passed away,” he says.

“It’s like Victorian mourning jewelry, but not as recognizable. The person wearing the jewelry knows, but people seeing the jewelry don’t know.” He uses dried flowers from the funeral, which are usually muted in tone, to make rings or necklaces for those left behind.
