Gemstones Found in the Ocean: The Beauty of Organic and Inorganic Gems

The ocean is home to a vast array of gemstones. Some of these gems are formed from the skeletons of tiny sea creatures, while others are created deep within the Earth’s mantle.

In this article, we will learn about the different types of gemstones found in the ocean, how they are formed, and their properties in polished and unpolished states.

Organic Gemstones

Organic gemstones are those that are created through the natural processes of living organisms. These gems are created from the shells, bones, and exoskeletons of sea creatures.

The most common organic gemstones found in the ocean are coral, calcite, aragonite, and pearls.

Coral

Coral is formed by the tiny coral polyps that live within colonies in the ocean. These creatures secrete calcium carbonate, which forms the coral reefs that we see in the ocean.

This process takes thousands of years and creates beautiful formations that are home to a diverse array of sea creatures. In the raw state, coral has a rough texture and a white, pink, or red color.

When polished, coral has a waxy luster and varies in color depending on the species. For example, red coral is highly valued in the jewelry industry and is often used to make necklaces, bracelets, and earrings.

Calcite and Aragonite

Calcite and aragonite are two forms of calcium carbonate that are found in the ocean. These minerals are often found in the shells of sea creatures like clams and mussels.

They have a wide range of colors, from white to yellow, gray, and even blue. In the raw state, calcite and aragonite have a dull, chalky appearance.

However, when polished, they can look stunning. Polished calcite and aragonite are often used in sculptures, ornaments, and jewelry.

Pearls

Pearls are one of the most iconic organic gemstones found in the ocean. These gems are created when a mollusk secretes layers of nacre around an irritant like a sand grain or parasite.

The layers of nacre build up over time, creating the smooth and lustrous surface of a pearl. In the raw state, pearls are unattractive and rough in texture.

However, when polished, they are transformed into beautiful gems that come in a wide range of colors and shapes. The most valuable pearls are those that have a round, smooth surface and a deep luster.

Inorganic Gemstones in the Ocean: Exploring the Wonders of the Deep

As we dive deeper into the ocean, the variety of inorganic gemstones found beneath its surface increases. These gems are formed through geological processes such as volcanic eruptions, hydrothermal metamorphosis, and various alterations that take place within the Earth’s mantle.

Here, we will discuss the different types of inorganic gemstones found in the ocean such as basalt, gabbro, peridotite, serpentine, and cassiterite, as well as the practices of diamond mining in the ocean. Basalt,

Gabbro, and Peridotite

Basalt, gabbro, and peridotite are essential components of the ocean floor and the Earth’s crust.

These three rocks are closely associated with one another and have a significant impact on the ecosystem of the ocean. They contain minerals such as olivine that are crucial for seafloor spreading and upper mantle activity.

Peridotite is a type of rock that makes up the upper mantle of the Earth and can be found on the ocean floor. Peridotite is unique in that it contains a mineral called peridot, which is commonly used in jewelry.

The green-yellow gemstone is created when peridotite comes into contact with molten rock and the resulting lava rapidly cools, causing the formation of small crystals of olivine. The stones are then cut and polished into a variety of shapes and sizes.

Gabbro is another igneous rock that is found in the oceanic crust. It is formed from molten lava and cooled slowly, which gives it a coarser texture compared to basalt.

In its raw state, gabbro has a dull appearance and a rough texture. However, when it is polished, it takes on a smooth and shiny surface with a range of colors, including black and gray.

Serpentine

Serpentine is a mineral that is often found in the ocean and is formed through hydrothermal metamorphosis. This process occurs when hot fluids from the Earth’s mantle interact with the oceanic crust and cause chemical changes in the minerals present.

The result is the formation of serpentine. In its raw state, serpentine has a dull, earthy appearance.

However, when polished, it takes on a smooth and waxy luster that is often used in sculptures, jewelry, and other decorative objects.

Cassiterite

Cassiterite is a mineral that is an important source of tin and can be found in both igneous and metamorphic rocks. The mineral forms through hydrothermal and magmatic processes and is commonly found in the oceanic crust.

In its raw state, cassiterite has a rough and crystalline appearance. However, when it is polished, it has a smooth and reflective surface that is often used in jewelry.

Diamonds

Diamonds are one of the most valued and sought-after gemstones found in the ocean. Despite their rarity, they can be found in several places across the globe, including the ocean.

Marine diamond mining is a common practice in many countries, such as Namibia, where most diamonds are found in shallow waters off the coast. The diamonds found in oceanic sediments are typically of lower quality compared to those mined on land.

However, some high-quality diamonds have been found in river transport deposits in the ocean.

Diamonds are formed through intense pressure and high temperatures deep within the Earth’s mantle, which is then exposed through volcanic eruptions. The process of diamond formation takes place over millions of years, with only a few diamonds making it to the Earth’s surface.

Other Findings in the Ocean

Aside from gemstones, the ocean floor also contains a variety of other minerals that have value for our society, such as gold, magnesium, and titanium. These minerals can be found in the sedimentary deposits of the ocean floor.

One of the latest trends in the deep-sea mining industry is the extraction of valuable minerals from the ocean floor. Mining companies use specialized equipment to break up the ocean floor and extract the minerals present.
