What You'll Learn
Plastic bags can cause discolouration
Plastic bags are a widely accessible and affordable storage solution for jewellery, but they can pose certain risks that could potentially damage your jewellery over time.
Plastics emit steam, which can cause pits and discolouration of the metal. This can also corrode the surface of pearls and certain other gemstones. Plastic bags don't allow air circulation, which can cause oxidation and discolouration of your jewellery pieces. This is particularly important for pieces with gemstones like sapphires or amethysts.
Some plastic bags, especially those made from PVC (polyvinyl chloride), contain chemicals that can react with jewellery metals, causing tarnishing or discolouration. These reactions are often slow and can go unnoticed until the damage has been done.
If you have no choice but to store your jewellery in a plastic bag, make sure to squeeze out all the air to prevent discolouration. You can also put silica packets in the plastic bag to absorb excess water.

Anti-tarnish plastic bags are an alternative
While storing jewellery in plastic bags is generally not recommended due to the potential for discolouration and corrosion, anti-tarnish plastic bags are an alternative. These bags are constructed of a special film that neutralises the corrosive gases that attack silver, platinum, gold, and other metals. This ensures that your jewellery remains lustrous and brilliant.
Anti-tarnish bags are commonly used throughout the jewellery industry to protect precious metals from discolouration and corrosion. They are designed with reinforced side seals to ensure the bags don't split when opened or filled. This makes them ideal for storing and organising jewellery, silverware, and other precious items. The bags are also reclosable, making it convenient to access the items inside without compromising their protection.
The anti-tarnish protection typically lasts for a minimum of two years, even with multiple openings and closings of the bag. When not in use, the bags themselves can be stored for up to five years and will retain their anti-tarnish properties. This makes them a cost-effective and long-lasting solution for jewellery storage.
In addition to bags, anti-tarnish protection is also available in the form of static intercept tabs and strips. These can be placed inside jewellery boxes or storage containers to provide long-lasting protection against tarnish and corrosion. This option allows for more flexibility in how you store your jewellery while still providing effective protection.
When using anti-tarnish bags or other anti-tarnish products, it is important to ensure that your jewellery is clean and dry before storage. This is because moisture and exposure to certain chemicals can still cause discolouration and degradation over time, even with the protection provided by the anti-tarnish treatment.

Plastic bags are not breathable
While storing jewelry in plastic bags may seem convenient, it is generally not recommended due to the potential damage it can cause to your precious items over time. One of the main issues with plastic bags is their lack of breathability. Plastic bags are made of materials that can trap moisture and chemicals, creating an unhealthy environment for your jewelry.
The breathability of a storage container is crucial in maintaining the condition of your jewelry. When jewelry is placed in an enclosed, non-breathable space, it is cut off from fresh air circulation. This can lead to a buildup of moisture and chemicals, which then come into direct contact with the jewelry's surface. Over time, this can result in corrosion and discoloration, especially for metal pieces and certain gemstones.
For example, pearls are extremely sensitive to the environment in which they are stored. When placed in a plastic bag, the lack of breathability can cause the pearls to deteriorate faster and lose their luster. Similarly, metals such as gold and silver can start to tarnish and become discolored when stored in non-breathable plastic bags.
Even if the jewelry is clean and dry before storage, the enclosed environment of a plastic bag can still contribute to discoloration and corrosion. This is because some plastics emit chemicals and vapors that can react with the metal and gemstone surfaces. These emissions can accelerate the deterioration process, leaving your jewelry with pits, discoloration, and a corroded surface.
To ensure the long-term health and preservation of your jewelry, it is advisable to opt for breathable storage solutions. Soft, breathable materials allow for air circulation, preventing the buildup of moisture and chemicals. By choosing appropriate storage options, you can maintain the beauty and longevity of your jewelry collection while also protecting your investment.

Plastic bags may corrode certain gems
Plastic bags may not be the best option for storing your jewelry. While it may seem convenient, it is important to consider the materials used in the jewelry's construction, its value, and the type of jewelry you want to store. Some plastics emit steam and chemicals that can cause pitting and discoloration of metals and corrosion of the surface of certain gemstones. This is because certain plastics emit vapors that contain corrosive gases, which can tarnish metals and damage the surface of some gems.
For example, pearls should be kept in a wooden box with felt lining and not in a plastic bag or box, as the plastic causes pearls to deteriorate faster. Similarly, opals, amber, and other natural gemstones should not be kept in plastic bags for long periods. The vapors emitted by plastic can also cause rhinestones and faux gems to corrode and lose their luster. Even anti-tarnish plastic bags, which are designed to protect jewelry from corrosion, may not be suitable for long-term storage of certain gems and are better suited for metals.
To ensure the longevity of your jewelry, it is recommended to store your valuables in a cool, dry place, away from direct sunlight and humidity. Choose breathable, soft materials and proper storage solutions, such as a high-quality jewelry box with sufficient padding. This will help maintain the beauty and longevity of your jewelry collection, especially for pieces made with sensitive materials or those that are emotionally valuable to you.
In summary, while plastic bags may be convenient for temporary storage or organizing small pieces, they are not ideal for long-term storage of jewelry, especially certain types of gems. The potential corrosion and discoloration caused by the chemicals emitted by plastic can damage the surface of gems and reduce their luster over time. Proper storage solutions, such as jewelry boxes or anti-tarnish bags, are better suited to protect and preserve your valuable jewelry collection.
