POULSBO — Every day this month, a resident of North Kitsap can win big on a genuine treasure hunt.

Such as Joanne Toizumi of Poulsbo, who found a silver dragonfly necklace last week after hearing of Dahlquist’s Fine Jewelry’s anniversary contest.

“I love dragonflies, so that’s why it made my day,” Toizumi said. “It was just really fun … Nobody in town has done anything like this.”

Richard Koven, owner of Dahlquist’s, said he posts simple clues on the store’s Facebook page (search Dahlquists Fine Jewelry, under Sampson Knight) around 10 a.m. every day. The jewelry store and design center is celebrating its 30th anniversary of business in Poulsbo with treasure hunts and sales during the month of September.

Koven said he wanted to thank the community for its support.

“We’re feeling [the recession] obviously, but since we have been here so long people seek us out,” Koven said. The store also offers custom jewelry and repair work onsite, and buys gold.

After the clue is posted — such as “On 7th Ave there is a Toy Store. Where is the free jewelry? Ask the nearby tree. Oh wait it is no longer there. I’m stumped”  — Koven said the prize is usually found within a half an hour.

“I’ve been told maybe I should toughen up my clues,” he said.

A note with the prize also tells the treasure hunter to come into the store for an additional prize, such as a gift certificate or jar of jewelry cleaner.

“Everyone who has received one has been overwhelmed and that makes me happy,” Koven said. “It’s an anonymous gift where anyone can be a part of the celebration, whether they’re a customer or not.”

Jessica Powell of Silverdale said she figured out the clues on two different days, but missed out on the first attempt when someone beat her to the location last week. She tried again the next day with success.

“Trying to decipher the clue first is the fun part,” Powell said, “then getting there before anyone else.” The clue pointed to Allen’s Cleaners & Laundromat in Poulsbo Village, where she went inside to claim her necklace.

Kingston resident and jewelry finder Emi Langworthy agreed that racing against other participants was a part of the fun.

“Of course I hit every red light” on the way to the hidden prize, Langworthy said. But the long-time Dahlquist customer, of course, made it in time.

“More companies should do things like this because it fosters good relations [with] potential customers,” Powell said. “And whose day is bad when you get a nice piece of jewelry?”
