Obsidian is a natural volcanic glass that is formed when lava cools quickly. It is not only heavy, but it is also brittle and has an irregular shape. This makes obsidian stones difficult to work with, so they are usually left in their natural form for decorative purposes. But what is the overall weight of obsidian? Read on to find out!
How Heavy Is Obsidian?
Obsidian is a naturally occurring stone that can be considered to be heavy in comparison to other naturally occurring stones. The weight of obsidian is determined by its weight per volume. Obsidian is defined as having a density of about .98 grams per cubic centimeter, which is very close to the average for most types of rocks and minerals.
When compared with other naturally occurring stones like granite, which is an igneous rock, obsidian is much heavier. Granite can weigh anywhere from .77 to about two grams per cubic centimeter.
However, the overall weight of the stone is also determined by how it is formed and processed naturally in nature as well as if it has been treated with manmade materials during its formation process. Obsidian can be formed in many different geographical locations which can all have an impact on how heavy obsidian is.
When treated with manmade materials, obsidian is also generally heavier. If it is not an untreated stone or if it is treated in any way during the natural formation process, then the final weight of the product is actually less than expected when compared to other stones.
Obsidian is mainly composed of silica and water which are both considered to be lightweight components. Due to their composition, obsidian is actually lighter than other stones which is why it is not considered to be one of the heaviest crystals available.
Some of the more lightweight types of rock can include shale rock and pumice stone both weighing less than four pounds per cubic foot while some of the heavier rocks include basalt.
What Factors Impact The Weight of Obsidian?
There are multiple factors that will impact the overall weight of obsidian. The type of obsidian is going to have a huge impact on the weight due to their varying compositions. The size or thickness of the stone is also going to be an important factor as well because if you have two stones that are exactly the same but one is smaller, it is obviously going to weigh less than its larger counterpart.
There are many different types of obsidian crystals and each type will weigh slightly different amounts based on how and where they are formed. Below are a few of the most popular types of obsidian:
Each different type of obsidian is known for having different healing properties and cultural importance. It is important to learn about the differences between each type of obsidian and then find out which would be the best option for your personal needs. You must look at the different types of obsidian if you are looking for how much obsidian costs as some types are rarer than others. For example, transparent obsidian is formed in a more unique way which makes it rarer and more expensive compared to other types.
Obsidian is one of the most popular types of crystals and is naturally occurring around the world which makes it more affordable and easier to buy compared to other types of stones or crystals.
