What To Know
- The way that opal changes color depends on several factors, including the type of opal, the angle at which the light is striking the opal, and the surrounding environment.
- The color that an opal changes to depends on the type of opal, the angle at which the light is striking the opal, and the surrounding environment.
- The value of an opal depends on several factors, including the type of opal, the size of the opal, the color of the opal, and the clarity of the opal.
Yes, opal does change color. This is due to the unique way that light interacts with the gemstone’s internal structure. When light strikes an opal, it is scattered in all directions. This scattering of light is what causes the opal to appear to change color.
How Does Opal Change Colour?
The way that opal changes color depends on several factors, including the type of opal, the angle at which the light is striking the opal, and the surrounding environment.
Type of Opal
There are two main types of opal: precious opal and common opal. Precious opal is the type of opal that is most likely to change color. This is because precious opal contains a higher concentration of water than common opal. The water in precious opal helps to scatter light more effectively, which results in a more noticeable color change.
Angle of Light
The angle at which the light is striking the opal also affects the way that the opal changes color. When light strikes the opal at a direct angle, the opal will appear to be more transparent. This is because the light is able to pass through the opal more easily. When light strikes the opal at an angle, the opal will appear to be more opaque. This is because the light is being scattered more effectively.
Surrounding Environment
The surrounding environment can also affect the way that opal changes color. For example, if the opal is surrounded by dark objects, the opal will appear to be darker. This is because the dark objects will absorb some of the light that is being scattered by the opal. If the opal is surrounded by light objects, the opal will appear to be lighter. This is because the light objects will reflect some of the light that is being scattered by the opal.
Why Does Opal Change Colour?
The reason that opal changes color is due to a phenomenon called diffraction. Diffraction is the bending of light as it passes through an object. When light strikes an opal, it is diffracted by the opal’s internal structure. This diffraction causes the light to be scattered in all directions. The scattering of light is what causes the opal to appear to change color.
What Colors Can Opal Change To?
Opal can change to a wide variety of colors, including:
- Red
- Orange
- Yellow
- Green
- Blue
- Indigo
- Violet
The color that an opal changes to depends on the type of opal, the angle at which the light is striking the opal, and the surrounding environment.
Is Opal a Valuable Gemstone?
Yes, opal is a valuable gemstone. The value of an opal depends on several factors, including the type of opal, the size of the opal, the color of the opal, and the clarity of the opal. Precious opal is the most valuable type of opal. Precious opal is typically larger than common opal and has a more noticeable color change.
