Yes, jade can turn brown. This happens due to a process called oxidation, which is a chemical reaction that occurs when jade is exposed to air and moisture.
How Jade Turns Brown
- Iron: Jade often contains trace amounts of iron. When exposed to air and moisture, the iron in jade can oxidize, causing it to turn brown.
- Sunlight: Prolonged exposure to sunlight can also cause jade to fade and change color, including turning brown.
- Improper Cleaning: Using harsh chemicals or abrasive cleaning methods can damage the jade's surface, leading to discoloration and browning.
- Age: Over time, jade can naturally develop a patina, which can appear brown. This is a sign of age and doesn't necessarily indicate damage.
Preventing Jade From Turning Brown
- Store jade properly: Keep jade in a cool, dry place away from direct sunlight.
- Clean jade gently: Use a soft cloth and mild soap to clean jade. Avoid using harsh chemicals or abrasive cleaners.
- Avoid prolonged exposure to moisture: Jade should not be submerged in water for extended periods.
Types of Jade That Can Turn Brown
- Jadeite: Jadeite is a type of jade that is known for its vibrant green color. However, it can also turn brown due to oxidation.
- Nephrite: Nephrite is another type of jade that can turn brown, particularly if it contains high levels of iron.
By understanding the factors that can cause jade to turn brown, you can take steps to prevent this from happening and preserve the beauty of your jade jewelry or objects.
