Turquoise jewelry, with its distinctive blue-green hues, offers a unique aesthetic. However, its beauty comes with a specific care requirement: it is a relatively soft, porous stone, making it susceptible to damage from improper cleaning methods. Understanding turquoise's properties is critical to preserving its color, luster, and structural integrity over time. The goal is to remove surface grime and restore shine without introducing harsh chemicals, excessive moisture, or abrasive forces that can lead to discoloration, dullness, or even cracking.
Understanding Turquoise: A Delicate Stone
Turquoise registers between 5 and 6 on the Mohs hardness scale, classifying it as a softer gemstone. Its porous nature means it can absorb oils, lotions, perfumes, and even chemicals from cleaning solutions, which can alter its color, often turning it greenish or darkening it permanently. This process, sometimes referred to as the "patina" or "living stone" effect, is not always desirable and can diminish the stone's vibrant blue. Additionally, sudden temperature changes or prolonged exposure to water can cause turquoise to crack or lose its natural oils, leading to a chalky appearance.
Essential Supplies for Safe Turquoise Cleaning
Before beginning any cleaning process, gather the correct, non-damaging materials. Using substitutes can result in irreversible harm to the stone.
- Soft, lint-free cloths: Microfiber or a very soft cotton cloth is ideal. Avoid anything abrasive.
- Distilled water: Tap water, especially hard water, can leave mineral deposits. Distilled water ensures a clean rinse.
- Mild, pH-neutral soap: Opt for unscented baby shampoo or a gentle castile soap. Harsh detergents or soaps with additives can strip the stone or leave residues.
- Soft-bristled brush (optional): A baby toothbrush or a dedicated jewelry brush can help dislodge dirt from crevices, but use with extreme gentleness.
- Cotton swabs: Useful for targeted cleaning in intricate settings or for applying minimal moisture.
Step-by-Step Guide to Cleaning Turquoise Jewelry
Gentle Surface Cleaning (For light dirt and everyday wear)
This method is suitable for turquoise that appears slightly dull from skin oils or dust, but isn't heavily soiled or tarnished.
Process:
- Dampen a soft, lint-free cloth with a small amount of distilled water. The cloth should be moist, not dripping wet.
- Add a single drop of mild, pH-neutral soap to the damp cloth. Work it into a light lather.
- Gently wipe the surface of the turquoise stone. Use light, circular motions. Avoid scrubbing.
- Immediately after cleaning, take a separate, clean cloth dampened with only distilled water and gently wipe away any soap residue.
- Pat the turquoise dry immediately with another clean, dry, soft cloth. Ensure no moisture remains, especially in settings or crevices. Allow it to air dry completely for a few minutes before storing.
Addressing Tarnished Silver Settings (Without harming turquoise)
When turquoise is set in silver, the metal often tarnishes faster than the stone gets dirty. Cleaning the silver requires careful isolation of the stone.
Method:
- Use a specialized silver polishing cloth. These cloths are impregnated with a mild polishing agent.
- Carefully rub only the silver portions of the jewelry, avoiding direct contact with the turquoise. The polishing compound in these cloths can be detrimental to porous stones.
- For intricate silverwork around the turquoise, use a cotton swab lightly dampened with a silver polish specifically labeled as safe for porous stones, or, more safely, use the edge of a silver polishing cloth. Ensure no polish touches the turquoise.
- Buff the silver with a clean, dry part of the polishing cloth.
Pro Tip: Never use chemical "dip" jewelry cleaners on turquoise. These solutions are highly acidic or contain strong chemicals that will permanently damage the stone's color and surface, leading to irreversible discoloration or a chalky appearance. Even if the turquoise is supposedly "protected," the fumes alone can be harmful.
What to Avoid: Common Mistakes That Damage Turquoise
Understanding what not to do is as crucial as knowing the correct cleaning methods.
- Ultrasonic cleaners: The vibrations can cause turquoise to crack or shatter, especially if it has natural fissures or is treated.
- Steam cleaners: High heat and moisture are detrimental to turquoise, potentially causing cracking or color changes.
- Harsh chemicals: Ammonia, bleach, chlorine, commercial jewelry cleaners (unless specifically formulated for porous stones like turquoise), and even household cleaning products will strip the stone's natural oils and cause permanent discoloration.
- Abrasive materials: Stiff brushes, abrasive cloths, or polishing compounds not intended for gemstones will scratch the relatively soft surface of turquoise.
- Prolonged water exposure: Do not soak turquoise jewelry. Its porosity means it will absorb water, potentially leading to swelling, cracking, or dulling.
- Direct sunlight or extreme heat: These can fade the color of turquoise over time and cause the stone to dry out and crack.
Preventing Future Damage and Maintaining Luster
Proactive care significantly reduces the need for intensive cleaning and prolongs the life and beauty of your turquoise jewelry.
Always put on turquoise jewelry after applying lotions, perfumes, hairspray, or makeup. These products contain chemicals and oils that can be absorbed by the stone. Remove turquoise jewelry before swimming, showering, washing dishes, or engaging in any activity that involves harsh chemicals or prolonged water exposure. Store turquoise pieces separately in a soft cloth pouch or a jewelry box with individual compartments. This prevents scratches from harder gemstones and protects them from dust and airborne contaminants. Regular, gentle wiping with a dry, soft cloth after each wear can prevent the buildup of oils and grime, minimizing the need for more extensive cleaning.
Maintaining Turquoise: Common Questions
Can turquoise change color over time?
Yes, turquoise can naturally change color, often shifting towards a greener hue. This can be due to absorption of oils from the skin, exposure to chemicals, or simply a natural aging process known as a "patina." While some changes are natural, improper cleaning or care can accelerate and intensify undesirable color alterations.
How often should I clean my turquoise jewelry?
For everyday wear, a quick wipe with a dry, soft cloth after each use is sufficient to remove surface oils and dust. A more thorough gentle cleaning with mild soap and distilled water can be done every few months, or when the stone appears visibly dull, but avoid over-cleaning.
Is it safe to get turquoise wet?
Brief, incidental exposure to water, such as during a quick hand wash, is generally not harmful if the jewelry is dried immediately. However, prolonged soaking, showering, or swimming with turquoise jewelry is strongly discouraged due to its porous nature. Water absorption can lead to cracking, dullness, or changes in color.
Can I polish turquoise to restore its shine?
Turquoise should not be polished with abrasive polishes or buffing wheels by an amateur, as this can wear down the stone and damage its surface. If your turquoise has lost its luster and gentle cleaning doesn't restore it, consult a professional jeweler specializing in gemstone repair. They may be able to re-polish or oil the stone safely.
