Introduction
Howlite is a naturally occurring mineral silicate that has been used for centuries in jewelry and other decorative applications. It is often compared to quartz, another popular mineral, due to their similar appearance. However, there are several key differences between howlite and quartz that make them distinct materials.
Appearance
Howlite is typically white or light gray in color, while quartz can be found in a wide range of colors, including clear, white, pink, and purple. Howlite also has a more porous surface than quartz, which gives it a matte finish.
Hardness
Howlite is a relatively soft mineral, with a Mohs hardness of 3.5. This means that it can be easily scratched or damaged. Quartz, on the other hand, is a much harder mineral, with a Mohs hardness of 7. This makes it more resistant to scratching and damage.
Durability
Because of its softness, howlite is not as durable as quartz. It is more likely to chip or break if it is dropped or subjected to other forms of impact. Quartz, on the other hand, is a very durable mineral that can withstand more abuse.
Cost
Howlite is a relatively inexpensive mineral, while quartz can be more expensive, depending on its color and quality. This is because howlite is more common than quartz.
Applications
Howlite is often used in jewelry, carvings, and other decorative applications. It is also used as a filler in some commercial products, such as paint and plastic. Quartz is used in a wider variety of applications, including jewelry, countertops, and electronics.

| Applications | Jewelry, carvings, decorative applications, filler | Jewelry, countertops, electronics, etc. |
Pros and Cons
Pros of Howlite
- Inexpensive
- Easy to work with
- Can be dyed to create a variety of colors
Cons of Howlite
- Not very durable
- Can be difficult to find in larger pieces
Pros of Quartz
- Durable
- Scratch-resistant
- Versatile
- Widely available
Cons of Quartz
- Can be expensive
- Can be difficult to cut and shape
Case Study
A study conducted by the University of California, Davis compared the durability of howlite and quartz. The study found that quartz was significantly more resistant to chipping and breaking than howlite. This study highlights the fact that quartz is a more durable material than howlite, making it a better choice for applications where durability is important.
Step-by-Step Approach to Choosing Between Howlite and Quartz
- Determine the application. What will you be using the material for? If you need a durable material for a countertop or other high-traffic area, quartz would be a better choice. If you are looking for an inexpensive material for a decorative application, howlite would be a good option.
- Consider the cost. How much are you willing to spend on the material? Quartz can be more expensive than howlite, especially if you are looking for a high-quality piece.
- Research the materials. Learn more about howlite and quartz before making a decision. This will help you understand the pros and cons of each material and make an informed choice.
Conclusion
Howlite and quartz are both beautiful and versatile materials that can be used in a variety of applications. However, they have different properties that make them more suitable for different uses. By understanding the differences between howlite and quartz, you can make an informed decision about which material is right for you.
