Rockhounding Sites in Hawaii: Where to Find the Best Rocks and Minerals

If you’re a rockhound looking for the best places to find unique and beautiful specimens, Hawaii is the place to go. This beautiful archipelago is home to a variety of rock formations and minerals, including some that are found nowhere else in the world.

In this article, we will explore the top rockhounding sites in Hawaii, the types of rocks you can expect to find there, and the most sought-after specimens.

Mahana Beach

Located on the western side of the island of Maui,

Mahana Beach is a popular spot for beachcombing and rock collecting. The beach is known for its beautiful black sand, created by the erosion of the nearby volcanic rocks.

Here, you can find a variety of minerals, including olivine (also known as peridot) and black corals.

Peridot is the birthstone of August and is known for its green coloration. In

Mahana Beach, you can find small pieces of peridot embedded in the black sand. Black corals, on the other hand, are a type of coral that grows deep in the ocean.

Some pieces of black coral wash up on the beach, making for an intriguing rockhounding experience.

Papakolea Beach

Another beach on the southernmost tip of the Big Island of Hawaii,

Papakolea Beach is famous for its unique green sand. This sand is made up of a rare mineral called olivine, which is formed as a result of volcanic activity.

Olivine is the same mineral that makes up peridot, but the green sand at

Papakolea Beach is coarser and more vibrant.

Green Sand Beach

Located on the southeastern tip of the Big Island of Hawaii,

Green Sand Beach is one of the rarest beaches in the world. This beach gets its name from the green-colored sand that covers the area, which is made up of a combination of olivine and basalt fragments.

Collecting green sand is an incredible experience and one that rockhounds should not miss.

Diamond Head

Located on the island of Oahu,

Diamond Head is a popular tourist attraction that also offers excellent rockhounding opportunities. The trail to the summit of

Diamond Head can be quite steep, but the effort is worth it for the stunning views of Waikiki and

Honolulu.

Along the way, keep an eye out for volcanic rocks, particularly those that contain small fragments of gold or silver.

Hualalai

The

Hualalai Volcano is located on the west coast of the Big Island of Hawaii and is an excellent location for rockhounding. This volcano is known for its basalt rocks, which can be used to make tools, weapons, and even jewelry.

Most of the rocks can be found near the crater rim, but make sure to exercise caution when collecting, as not all areas are safe to explore.

Honolulu

For those who prefer city exploring to beachcombing,

Honolulu is a great spot to find unique rocks and minerals. There are several rock shops in the city that offer excellent collections of rocks and minerals from Hawaii and around the world.

You can find everything from polished Labradorite to rough-cut agates and geodes.

Types of Rocks Found in Hawaii

Hawaii is a unique location to find a variety of rocks, thanks to the volcanic activity that has molded this beautiful archipelago over time. Here are some of the most common types of rocks you can expect to find in Hawaii.

Igneous rocks in Hawaii

Igneous rocks are created when magma or lava cools and solidifies. Hawaii is home to many types of igneous rocks, including obsidian, geodes, gabbro, basalt, and agates.

Geodes

Geodes are spherical rocks that have a hollow cavity lined with minerals. They are formed when gas and water vapor become trapped in the lava as it cools, creating a perfect environment for crystal growth.

Gabbro

Gabbro is a dark-colored igneous rock that is formed deep beneath the earth’s surface. It is usually coarse-grained and can contain minerals like olivine, pyroxene, and plagioclase.

Basalt

Basalt is a fine-grained igneous rock that is formed from the solidification of lava. It is usually black or dark brown in color and can have a smooth or rough surface.

Agates

Agates are a type of chalcedony that is formed in volcanic rocks. They come in a variety of colors and patterns and can be polished to make jewelry or decorative items.
