If you’ve ever wanted an opal — it’s time to visit Spencer

  Published at  | Updated at

SPENCER — The tiny community of Spencer has been a landmark destination in northeastern Idaho for decades.

Home to one of Idaho’s most treasured gems — the Spencer precious opal — the town enjoys a steady stream of visitors that come to the area to dig and hunt for the multicolored gemstones.

But some things are changing in Spencer, a combination of illness and retirement among several shop and mine owners means several venues could close or decrease hours. Other stores however, report that business remains the same as usual.

EastIdahoNews.com talked with several shop owners about their businesses and the future of the community.

Opal Mountain Mine

“I really can’t mine anymore, and after 25 years we will be soon be full-time Californians,” Bob Thompson of the Opal Mountain Mine said early in August. “Susan and I sold the mine about two months ago and are discounting our finished stones, trying to sell our inventory as the new owner probably won’t open it.

The Thompsons sold their mine to Pete Jeppesen, originally from Idaho Falls, but now of Alaska.

Bob and Susan Thompson are retiring after 25 years mining and cutting opal in Spencer.

“We understand that Pete will only operate the mine a few weeks during the summer and will not be operating the store,” said Thompson. “The opal kept the store open, but it has taken a toll on us over the years.”

Over the past 25 years, Bob and Susan have had some memorable stones produced from their mine. The largest precious opal found by them was rock that weighed about 2 pounds. They still proudly display it. Their largest cut stone, measuring 78 by 58 mm, is in the Smithsonian.

One of their specialties is the star opals, which feature three to six rays running from the center to a light on the edge of the gem.

Hot Rock Gems


Steve Beard of the Hot Rock Gems shows a nice piece of “ice cream” opal.

Hot Rock Gems is owned by Boneta and Brent Sudweeks, but due to health problems, they are helped in their mines and shop by Steve Beard.

“We get our (precious) opal from the Thompson mine, and we hope that continues with the sale,” Beard said. “But we have a common opal mine about 15 miles west of here that produces a white, pink and brown opal called ‘ice cream opal.’”

Precious opal lies in layers and to make the gems, they can be backed with other rock and capped by a clear stone, which creates a “triplet.” The ice cream opal is a common solid opal with less water content in it, allowing the semi-precious gems to be a solid piece.

High Country Opal, Gems and Jewelry

Jackie Hooper of the High Country Opal, Gems and Jewelry store, explains how the precious opal is formed in the rocks near Spencer.

At High Country Opal, Gems and Jewelry, Jackie Hooper runs the store by herself since her husband, Dennis, has become ill and cannot work the stones anymore.

“We have enough rough material for me to continue doing this for the rest of my life,” Hooper said. “We got most of our material from the Thompson mine when it was owned by Lickenwalter. Dennis had a towing business but helped him mine the opal and was paid in stones rather than money.”

The Hoopers have bought some material from the Thompsons after he bought the mine from the previous owner. Jackie does most of the work on the stones, but her son, Kraig Smith, builds the sets and sets most of the stones.

Spencer Opal Mines and Opal Country Café

Hayden Pearson of Salt Lake City found his opal at the “mini-mine” and has on the required safety equipment while searching in the rough rock pile.

Spencer Opal Mines and Opal Country Café is owned by Claudia and A.J. Couture.

It’s the original mine that opened in 1968, and the family says Spencer Opal Mines and Café isn’t changing as at. Daughter Erin Mortensen said the mine has been in the family for four generations and her younger children are already making plans to take over the venue.

“We don’t have plans to go anywhere,” Mortensen said. “We’ve already got plans, and we’re coming up on our 50-year anniversary.”

Spencer Opal Mines is unique because it includes a “mini-mine” behind the café where from 10 to 70 “would-be miners” daily search for opal in a pile of rock brought down from the business’s 20-acre mine eight miles east of Spencer.

“We have the original mine and the largest one,” Claudia said as she hurried around the store. “Due to insurance, we cannot let visitors in the mine to hunt the stones, so we bring material down here for them to search through.”

Groups like Boy Scout troops, schools and family reunions often come to search for the opals.

“We wanted to have a little fun that is different for our family reunion,” said Valerie Dunn of Saratoga Springs, Utah, as she cracked open the stones that looked promising. “Jamie (her daughter) has found a good one, and my nephew, Hayden (Pearson), also got one.”

The store’s website contains a list the charges and rules for digging there.

Jackie Hooper holds rough samples of the rare pink precious opal on the left and the more normal green, blue and red on the right.

One thing all of the owners and miners of the precious opal have in common is their keeping the best and unique stones they find. The Thompson’s have their “Bob’s Star” and the 2-pound gem, while Jackie Hooper has her rare pink solid precious opal ring.

As the future of the Spencer opal changes, it is unclear what will happen to the shops and mines. Hot Rock Gems and High Country Opal, Gems and Jewelry, are the only two shops that are open year round. Spencer Opal Mines and Café is open full time from Memorial Day through Labor Day with reduced hours during April, May and October, but then closed during the winter months.

As the city changes, residents are optimistic new ownership of shops and mines may be a good thing for the community. Whatever happens though, residents are sure the Spencer precious opal will continue to attract tourists and gem hunters for years to come.

These finished “triplet” stones are priced by their color, size and clarity.
