The Three Types of Stones

There are 3 primary stones from which beach stones and all other precious stones get their origin and mineral properties. They are namely Sedimentary, Metamorphic, and Igneous stones.

Sedimentary stones

Sedimentary stones
Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Amnh.org

They form in layers because of clay, sand, or mineral particles carried by water or air. The limestone is an example of a Sedimentary stone.

These particles may be specks of dust, matter, or small chips from old rocks. There are three types of Sedimentary stones, Clastic, chemical, and organic.

Metamorphic stones

Metamorphic stones are pre-existing stones that morph (transform) into their current state due to heat, moisture, and pressure.

During the morphing process, metamorphic stones carry mineral properties from their source and gather new ones. Examples of metamorphic rocks include schist, marble, and slate.

Igneous stones

Igneous rocks are formed from melted rock deep inside the Earth.

Igneous stone occurs when a molten rock or lava from a volcanic eruption suddenly cools down. The process is exothermic and involves a state change from liquid to solid.

A characteristic of igneous stones is the presence of large crystals. These crystals get their size due to the amount of time the molten magma cools off under the ground.

 

Identifying Beach Stones

To properly identify and determine the authenticity, durability, and quality of the beach stones you have in your possession, here’s a list of tests you need to do on your collectibles. If your gems successfully pass these tests, you can move on to the next stage.

The Water Test

To enable you to get a detailed look at its color, formation, and mineral composition, you must first wet your stone.

Some beach stones are unique. You can tell their mineral composition from their color. An example is the amethyst stone. (a purple-colored gemstone)

The Surface Test

After a successful water test, you must then proceed to examine the surface of the beach stone. Check whether it is waxy, metallic, or glassy. Some stones are also magnetic. You must check for that too and confirm with a magnet.

If you encounter difficulties with weathered surfaces, you can use a hammer to break the stone and see the luster. Observing the luster in the stone can also help you determine the texture of the stone’s surface.

Crystal Shapes Test

Most stones have crystals inside them. These tiny crystals take different shapes and form like pyramids, prisms, cubic and fine needles.

But you can’t see with your naked eye. You need the help of a magnifier to help you spot the crystals easily.

The Mineral Streak Test

Get a porcelain tile and turn it to the plain side. Drag your beach stone on this surface with enough pressure so that it leaves a colored line.

From the colored line, you get information about the stone you are holding and its mineral composition.

The Mohs Scale Test

The test is also known as the hardness test. You need a coin, a nail, and a broken glass chip for this test.

After scratching the stone surface with each object, you must record their effect and compare it with details on the Mohs scale. The Mohs scale has a range of numbers to determine the hardness of a stone based on the presence or absence of marks by these sharp objects.
It is a hard stone if the nail, coins, or glass leaves no marks on the surface. The hard the stone is, the higher the durability and the higher the value.
