Spencer Opal Mine Cafe


Located off of Old Highway 91 in Specner, Idaho is what looks like your typical run of the mill cafe. However, Spencer’s is not your typical eatery. Located in the back of the building is a large rock pile where customers can go and opal mine to their dismay. You will pay for your findings per the pound at extremely reasonable prices.

How does it work?

When heading into the back, you will be given a spray bottle, with water in it, and a bucket. When looking through the rocks, you will be looking for a cream/white with streaks of vibrant colors. To see if you have found an opal, you will spray the rock with water and hold it into the sun. If colors deflect from the stone, it is an opal!

Protip: to cut costs, you can use a pick axe to remove the rock exterior from the opal (which reduces the weight of it).

Where do the rocks come from?

The actual opal mine is located a few miles from the cafe but it is too dangerous for civillians to go into. The miners will then fill a large dump truck with the debris and unload the truck in the back of Spencer’s! A new truck load comes regularly so that the customers are alwyas able to find their jewels.
