Visit the Opal Mines

At Spencer’s Opal we try to bring the beauty of Opals to life. Our top of the market miners help us mine beautiful opals, just for you. Then they are washed, polished, and cut to make a variety of jewelry and gifts.


Introducing our new fresh for the summer menu: we will be doing fabulous soups, fantastic salads, and phenomenal sandwiches! Stop at our famous café and grab a bite to eat. We serve meals for breakfast, lunch, and dinner.
