Facts about Rocks, Gems and Minerals: How They Could be Different

The forming of rocks gems and minerals is started when the volcano erupts. The magma from inside the earth comes out to the surface. It flows along the volcano’s contour and cools. The chemical elements contained in magma forms the crystals. Then, minerals from the magma change gradually with the high pressure and temperature and become new minerals. In the present days, more than 3,500 minerals have been discovered. Minerals, then, are changed into two new forms: gemstones and rocks. The question is “what are the differences between gems, rocks, and minerals?”

Facts about Minerals

To find out the differences between minerals, gems, and rocks, let’s start by defining each of them. Mineral is a naturally occurring substances. The forming process of mineral involves geological process. Mineral, furthermore, contains some chemical characteristics and compositions of physic. The high order of atomic structure in mineral is crystalline in normal way. The branch of common sense that focuses on minerals is mineralogy. From mineralogy, we can tell the constitution of a mineral.

How to Value Minerals

Rocks Gems and Minerals

To value the minerals, we can learn the important properties we will find inside minerals. Those properties are: transparency, color and intensity, crystal formation, repairs and damage, size, locality, luster, anomalies, Matrix presence, demand, rarity, trimming and cleaning. As mineral has intense color and eye catching, the minerals are highly valued. We can see Rhodochrosite as the example. Because of the striking color, Rhodochrosite has a high value. Transparency also increases the value of mineral. As minerals are more transparent, the value will be higher. The other properties mentioned previously determine the value of minerals. As the definition and properties of minerals have been elaborated, we get some inspiration related to rocks gems and minerals.

Facts about Rock

To get more brief differences between minerals, rocks, and gems, let’s find out the facts about rock. The accumulation of mineral with no specific chemical composition is a brief definition of rock. The range of mineral in rock is between pure elements and simple salt to thousand forms with very complex silicates. The rock, furthermore, is divided into three big types: igneous, sedimentary, and metamorphic rocks. To understand the earth formation, it is important to learn the science of rocks. It is petrology.

Facts about Gemstone

As we have collected the definitions and facts about minerals and rocks, let’s do the same for gemstone. The definition of gemstone is striking and valuable minerals which are cut and polished. Then, those cut and polished minerals are used as ornaments or jewelry. Gemstones have some physical properties such as hardness, rarity, color, and others. To study the special physical and optical properties of gemstones, we can learn gemology. It is the branch of mineralogy. The basis of gemology is human value judgment that determines the gemstone is valuable or not.

It can be concluded that…

From those definitions and facts about minerals, rocks, and gems, we can find out that they have differences. We can conclude from those facts of rocks gems and minerals. The conclusions are that minerals become crystalline; minerals accumulate to become rocks; and gemstones are human’s judgment to minerals whether minerals are valuable and attractive or not. It can be said that gemstone is a decently invention of human.

Description: Rocks gems and minerals are basically minerals. Through some process, rocks and gemstones are developed from the minerals. The facts show that they have their own specialty.
