Idaho is known worldwide for its exceptional-quality potatoes. But no, this article isn’t about the popular tuber. The state is recognized for other things:  scenic mountain landscapes, miles of protected wilderness, and huckleberries, to name a few. Did you know that Idaho is also called the Gem State? Because more than 72 precious and semi-precious gems have been mined from this state since the 1800s.

Over the years, the state east of Washington has produced a diversity of important gems. Gems are precious or semi-precious stones that can be cut or polished for ornamental purposes. Today, gems are not only used for decorating purposes. They are popularly utilized for healing, cleansing, and other soothing properties.

Some of the Idaho gems and their benefits:


Since the late 1800s, garnets have been found in Idaho in sands and gravel of placer deposits and metamorphic rocks. They are produced on these rocks or on the soil formed above them. Most were found among the gravel layers in the sediments in many of this state’s streams. They are commonly in deep red and purplish-red variety.

Idaho’s most prized gem is the star garnet. These are extremely rare. Other than in this part of the world, they can only be found in large quantities in India. Star garnets are purplish-red almandite that showcases four or six-ray stars after being cut. In 1967, it was designated as the official state gemstone.

Garnet is said to detoxify the blood and keep the heart healthy. It also enhances the strength of other organs such as the spleen, lungs, and spine. Wear it as a piece of jewelry, primarily as a pendant, so it lies over your heart.


Opal has been found in various locations in the state. They have also been mined and produced since early 1900. This gemstone’s beauty lies in its ability to create every color from the spectrum when exposed to lights from different angles.

Opal is associated with luxury and relationships. It is said to bring prosperity and a good reputation in society. Believed to aid in helping your tourism and travel businesses, it also helps in clearing debts and litigations.  Opal is best worn as a ring on your right hand. Activate and cleanse your opal before use to remove its impurities.


Like the Opal, Jasper is prevalent in many locations in Idaho. Bruneau Jasper is the most famous. Its color ranges from brown to brownish cream and red to reddish cream. It is commonly marked with sweeping curves and ovals.

Jasper is known to be a nurturing stone. It confers patience and understanding and brings comfort and reassurance to its wearer.


Ruby is a natural deep pink or blood red precious gemstone of the Corundum family. They are rare but can be found in several counties in the Gem State. Rubies are recommended to be worn to improve self-confidence. They are commonly worn as a ring on the ring finger of the right hand.

Rocks, crystals, and minerals are also found in Idaho:


Various types of this beautiful rock can be found in Idaho. Usually, they are discovered in counties and creeks. They can be seen in light blue, red, green, and different specimens like branded, scenic, dendritic, polka dot, smokey, and moss.

Agates are valued for their iridescence. They are considered semi-precious stones and are attractive enough to be used as jewelry.


Geodes are rock structures with an internal cavity lined with mineral materials. The ones found in the state range in size. Gigantic ones are found together with diamonds. Tiny geodes are made into pieces of jewelry.  Bigger ones are polished as decorative items for the home or office.


Black-variant obsidian is typically found in the southern and central regions of Idaho. Often found in tiny sizes, they are commonly used to create a shield of protection to ward off negative or harmful energies.


Amethyst and clear quartz are often found together in the Gem State.  Amethyst is a violet variety of quartz. It is known as the “all-purpose stone,” which helps to relieve stress, anxiety, headaches, and fatigue. Clear quartz is a famous stone, commonly used together with other crystals. It purifies energy and helps in manifestations.


Topaz is a colorless gemstone used in jewelry and other adornments. You can find several types of topaz in the Gem state, particularly the blue and yellow variants. Trace element impurities can make it pale blue, golden brown, and yellow-orange. Topaz brings joy, generosity, abundance, and good health to those who wear it.

Petrified wood

Petrified wood is pieces of wood, like hardwoods and conifers, mineralized by gems. They are found where various gemstones were also produced.


You can find horse, plant, and zoisite fossils in different counties in Idaho. Fossils make you feel connected to ancient history. Mixed with minerals, they become attractive pieces that can be utilized as decors in your space.
