Do Amethyst Fade? (Explained & How to Avoid)

In this post, we will discuss do amethysts fade and explore issues such as how it gets their color, whether it fades in sunlight, change color by heat, and whether a faded amethyst can be restored.

In addition, we will provide practical tips for preserving the color of amethyst gemstones.

Does Amethyst Fade?

Yes, amethyst can fade.

Amethyst is a type of quartz, known for its deep purple color. The color of amethyst is caused by the presence of iron impurities. When amethyst is exposed to sunlight or UV radiation from other sources, the iron impurities are destroyed, causing the color to fade.

How Does Amethyst Get Its Color?

Amethyst is composed of silicon dioxide.

It has a very beautiful purple hue due to the presence of trace amounts of iron and manganese in the crystal.

Due to its geological origin and conditions of formation, amethyst is not a single color.

It comes in a variety of colors, including light purple, lilac purple, lavender purple, greenish purple, descending purple, fuchsia, and deep purple.

How do these fascinating purple colors in amethyst come about?

There are two main factors:

One is gamma rays (γ).
The other is the presence of trace amounts of trivalent iron ions (Fe3+) in the crystal’s lattice.

Neither of these two factors can create the fascinating color.

To be more specific,

As we know, gamma rays have an extremely high penetrating power and high energy content.

Therefore, when a crystal located deep underground is exposed to gamma rays, if the crystal lattice happens to contain a small amount of trivalent iron ions, then these clusters of atoms containing trivalent iron ions lose an electron and form a hole, which is often referred to as the Color Centre in crystallography.

This cluster of atoms absorbs visible light and forms the beautiful amethysts that we can see with our naked eyes.

If these amethysts are heated to 300-400°C, the electrons of these atomic clusters will be released and the attractive color of the amethyst will disappear.

Does Amethyst Fade in Sunlight?

Exposure to sunlight is a common problem when it comes to preserving the color of amethyst.

Although amethyst is usually stable under normal light conditions, prolonged exposure to direct sunlight can cause its color to fade over time.

It is important to note, however, that the fading process is usually slow and may take several months or years for a noticeable change to occur.

Does Amethyst Change Color with Heat?

Yes, amethyst can change color with heat.

When an amethyst is heated, the iron impurities in the amethyst can be rearranged. This can cause the color of the amethyst to change. For example, an amethyst that is heated to a high temperature can turn yellow or brown.

This phenomenon is often irreversible, so it is critical to handle amethyst gemstones carefully during jewelry repairs or other high-temperature processes.

Can Amethyst Fade?

Yes, amethyst can fade.

Fading of amethyst is a gradual process, so it may take months or even years to see a change in color.

If amethyst is heated frequently, it loses its moisture rapidly, which makes it prone to turning white.

Studies have found that when amethyst is heated to 300-400°C, the purple color fades and turns yellow.

It is best not to leave it in a hot environment, let alone expose it to bright light, as this may affect its color. It could also be due to corrosion caused by frequent exposure to chemicals, which can also affect its quality.

Why is My Amethyst Losing Its Color?

1. Caused by heat 

If it is often placed in a hot environment, it will easily turn white.

Therefore, during regular wear, it should be kept away from a high-temperature environment and not exposed to strong light for a long period of time.

2. Chemical corrosion 

Since amethyst is a collection formed by the crystallization of various mineral particles, if it is often in contact with strong alkaline or acidic chemicals, it will form a certain corrosive effect and the surface will turn white.

You should try to avoid contact with shampoo, shower gel, alcohol, vinegar, and other items, so as not to affect the surface color.

3. Due to oxidation

If you don’t clean it on a regular basis, after wearing it for a long time, the surface will be prone to oxidation and thus become white.

It is best to pay more attention to cleaning during daily wear, and when there is a lot of dirt on it, scrub it clean in time so that it can maintain the original luster of amethyst.

How Long Does It Take for Amethyst to Fade?

The time it takes for amethyst to fade depends on the amount of exposure to sunlight or other sources of UV radiation.

Amethyst should not be exposed to sunlight for long periods of time, but it usually takes several months or years for the color to fade.

It should also not be placed in other hot environments, such as bathrooms or saunas, as its color will fade or even dissipate.

After using amethyst, you should wipe it with a soft cloth and store it in a storage box.

Can Fade Amethyst Be Restored?

Unfortunately, once the color of amethyst has faded, it is very difficult to restore it to its original vibrancy.

The fading occurs as a result of the breakdown of impurities in the crystal structure, and this change is often permanent.

However, professional gemological treatment methods, such as heat treatment, can enhance the color of faded amethyst to some extent.

It is essential to consult a skilled gemologist or jeweler who can assess the condition of the stone and provide appropriate advice.

How to Keep Your Amethyst from Fading?

To prevent your amethyst from fading, you should store it in a dark place and avoid exposure to sunlight or other sources of ultraviolet radiation.

The following are some practical tips for your reference:

• Minimize sunlight exposure: Store your amethyst jewelry in a cool, dark place out of direct sunlight, especially when not in use.
• Use protective storage: Consider using a jewelry box or pouch lined with soft fabric to protect amethyst pieces from light and potential scratches.
• Avoid harsh chemicals: Keep amethyst jewelry away from chemicals such as detergents, perfumes, and hairsprays, which can accelerate fading.
• Gentle Cleaning: Clean your amethyst with mild soapy water and a soft bristle brush. Avoid ultrasonic and steam cleaning methods as these may damage the stone.
• Regular inspections: Check your amethyst jewelry regularly for signs of discoloration or damage, and seek professional help if needed.
• Professional guidance: Consult a reputable jeweler or gemologist for advice on the proper care and maintenance of your amethyst jewelry.

Does Green Amethyst or Pink Amethyst Fade?

Green amethyst, also known as quasi-amethyst, and pink amethyst are unique variations of quartz. Although their color origin is different from that of traditional amethyst, the fading concerns are similar.

When exposed to excessive sunlight or harsh conditions, both green and pink amethysts will experience fading. Therefore, the same precautions mentioned earlier must be taken to protect their color.

Conclusion 

Amethyst, with its enchanting violet hue, is a gemstone that has fascinated people for centuries.

Although amethysts usually retain their color well under normal circumstances, precautions must be taken to prevent fading caused by sunlight, heat, and other factors.

By understanding the science behind the color of amethyst, practicing proper storage and cleaning techniques, and seeking professional guidance when needed, you can maintain the beauty of your amethyst jewelry for generations to come.

Remember, a little care goes a long way when it comes to maintaining the timeless appeal of this fascinating gemstone.
