Rare Gems and Minerals in Washington

Washington is a rock collectors paradise. There are many different gems and minerals that can be found here. There are many remote locations that require hiking to access but will still produce some nice quality specimens of a variety of types.

Petrified Wood



Petrified wood is the state gem of Washington. It can be found all throughout the state.

The most well-known site for petrified wood in the Gingko Petrified Forest State Park is in Vantage, Washington. This is a very rare petrified forest where the wood is found imbedded in basalts. Unlike many petrified forests which were believed to have been covered by lava flows, the now petrified trees found in the Gingko Forest are thought to have been submerged underwater, which preserved them in wonderful condition.

Saddle Mountain is Grant County is a popular area for collectors to search for petrified wood. Some of the specimens found here have opalized wood. The site is managed by the Bureau of Land Management.

There are many sites where petrified wood is found that have received very little attention. You can find specimens searching along riverbeds in much of the state.

Amethyst/Quartz Crystal





In Snohomish County, you can find quartz crystals at Cedar Ponds near Sultan. Most of the crystals here are clear, but occasionally amethysts are also found. Some locations where the crystals are found are very remote and require extensive hiking to find them. Hiking and getting away from the crowds will often help you find them better specimens.

There are quite a few places in King County where quartz can be found. Several locations around North Bend are popular for exploring. Quartz varieties found are generally clear or smoky, but occasionally nice purple amethysts are also found. Denny Canyon is one of the good areas to look, as well as Hansen Creek and Bessemer Ridge.

Over the mountains in Okanogan County is another excellent area to explore and search for crystals. Quite a few locations will produce fine quality specimens if you look hard enough.

Additional collecting sites are found in Kittitas County, Lewis County, and Pend Orielle County, among others.



Jasper



Washington is also ranked among the places in the United States of America where the stone can be found. Sightings of jasper have been located in areas like; Clallam County, Grays harbor County, Jefferson County, Klickitat County, Lewis County, Pacific County and Skamania County.

Agates



Agates are abundant throughout Washington State and are one of the most popular stones for collectors to search for. There are countless locations where beautiful agates occur.

The bars along the Columbia River are great places to search for agates. These stones are generally smooth and polished with nice colors. Near Richland and Pasco is one place where it can be easy to find them in the right areas.

The ocean beaches are perhaps the most popular place to search for agates. They can be found just about anywhere along the coast, although there are certain beaches that have a good reputation for being especially productive. Some nice amber colored agate specimens are known to occur around Damon Point. The beaches along the Olympic Peninsula at Agate Beach will also produce some nice finds.

Timing the tides will help you when searching for agates at the beaches in Washington. Looking after winter storms is generally the most productive.



Jade



Washington is one of the few states in the U.S. that produces Jade. There are some nice jade specimens that are found from time to time, and they can be quite valuable. Some high quality pieces are even exported to Asia for that collectors market. However, many specimens are of little value, and not all jade is created equal.

Jade is one of its kind gemstone that is found in metamorphic rock. Jadeites are a peculiar kind of rock that hosts compounds like sodium rich pyroxene and is a hard stone. On the other hand, nephrite, another form of Jade is a softer stone, consists of prism like structure made of calcium, magnesium iron and some more impurities.

The basic green color of Jade comes from the amount of iron present in the stone. However, Jade is also available in black, orange, grey, yellow-brownish, blue, mauve, pink-lavender and white.

In ancient times, jade was used in making armory tools. The name of the stone is derived from a Spanish word “piedra de ijada”, which means “loin stone”. In the spiritual world of gemstones, Jade is known as the stone of attraction. It is believed to have properties that attract money and love towards one. The gem has also been associated with the healing of kidney stones since the prehistoric period.

Jade is actually found in both forms in Washington; jadeite and nephrite. Most people assume all jade is light green, but it actually comes in a variety of colors such as black, grey, olive, yellow, etc.

There are quite a few locations where it can be found, such as Whidby Island near Oak Harbor, along the Skagit River, Deer Creek near Oso, river banks around Wenatchee, and the Blewett Pass area are all known locations where jade can be found. The best places to search are bars along rivers and creeks.

Opal



The lava buttes in the Wind River locality, which is about 17 miles north of Carson are said to contain some opals. Precious opal is also found in the Lincoln County and common opal in the Quincy region of Grant County.

The basalt flow that occurs in Washington appears to have served as confining layers for silica-rich water distribution in underlying sediments. For opal deposit to be formed, a source for soluble silica is required.

The first significant opal discovery in the United States was near Whelan, Washington. Some specimens were recovered by a farmer digging a well. For a short time there was a rush to the area, and gem miners were searching for opals. This was relatively short lived, and most of the opals from this location were mined out.

Fossils



In addition to the abundant petrified wood that can be found all throughout Washington, other types of fossils also occur here.

The most famous fossil in Washington is the Columbian Mammoth, a beast that roamed the state over a million years ago. Tusks and skeletons have been found on the Olympic Peninsula.

Crab fossils of excellent quality have been found in southwest Washington in the Strait of Juan de Fuca. This area also has an abundance of other marine fossils including clams, coral, shells, and sea snakes.

Plant and insect fossils can also be found in numerous locations throughout the state.
