Can Yellowed Pearls Be Whitened?
Pearls can turn yellow over time due to exposure to heat, light, chemicals, or even being left unworn for too long. When not correctly cared for, the organic nacre that gives pearls their shine can dry out and lose its lustre. Storing pearls in airtight containers or exposing them to perfumes, hairspray, or household cleaners can also speed up yellowing.
Materials Needed
To clean your yellowed pearls safely at home, you’ll need the following items:
- Mild, non-alkaline soap (e.g., baby shampoo)
- Lukewarm water
- Soft, lint-free cloth
- Small bowl
- Soft-bristle brush (optional)
Step-by-Step Cleaning Methods
The following methods, including insights from the Gemological Institute of America (GIA), will help you clean your yellowed pearls without risking damage to the delicate nacre—the layer that gives pearls their shine.
1. Mild Soap Solution Cleaning
- Instructions: Mix a small amount of mild soap with lukewarm water in a bowl. Dip a soft cloth into the solution and gently wipe each pearl, being careful not to soak the entire piece of jewellery. Pearls should never be submerged in water for long periods, as the silk thread can weaken.
- Rinse: Wipe the pearls with a damp cloth that has been dipped in clean water to remove any soap residue.
- Dry: Lay the pearls flat on a soft towel to air dry completely before storing them. Make sure they are thoroughly dry to prevent damage to the thread.
2. Soft Brushing for Stubborn Spots
- Instructions: For areas with stubborn dirt, use a soft-bristle brush (like a new makeup brush) to gently brush the pearl’s surface. Be careful not to use too much pressure, as this can damage the nacre.
Common Mistakes to Avoid
- Avoid Harsh Chemicals: Never use harsh chemicals like bleach, ammonia, vinegar, or rubbing alcohol. These substances can erode the nacre and cause lasting damage.
- No Ultrasonic Cleaners: Ultrasonic jewellery cleaners can damage pearls due to vibrations and heat. Always opt for manual cleaning methods.
- Avoid Submersion: Don’t submerge pearl jewellery in water. Prolonged exposure to moisture can weaken the silk thread.
- No Abrasive Materials: Avoid using rough cloths or brushes. Even tissues can be abrasive and scratch the pearls’ surface. Always use a soft, lint-free cloth.
Storing Your Pearls
- Store Separately: Pearls are soft and can easily be scratched by other jewellery. Store them separately in a soft pouch or a fabric-lined jewellery box.
- Keep Pearls Hydrated: Pearls contain a small amount of water, so they need to stay hydrated to prevent drying out and cracking. Avoid storing them in airtight plastic bags or arid environments.
- Avoid Heat and Light: Keep pearls away from direct sunlight, heating vents, or extreme temperatures, which can damage the nacre and cause discolouration.
Can Yellowed Pearls Be Whitened?
Yes, but only gently and gradually. Pearls that have gone yellow over time can sometimes be lightened with careful cleaning. Use a soft cloth and mild soap solution — never bleach, baking soda, or vinegar, as they will damage the nacre.
If the yellowing is deep or permanent, it may not be fully reversible. However, regular care and proper storage can help improve the appearance and prevent further yellowing.
