| Care |
Both natural turquoise and natural African turquoise are beautiful stones, but they have key differences that affect their care. It's important to know the distinction as "African turquoise" is actually a type of jasper, not true turquoise.
Understanding the stones
Natural turquoise
Composition:
• Formed by the combination of copper and aluminum phosphate.
Hardness:
• Ranges from 5-6 on the Mohs scale, making it relatively soft and prone to scratches.
Porous:
• Natural turquoise is porous and can absorb oils, liquids, and chemicals, leading to discoloration. This is particularly true for lower-grade turquoise; higher-grade turquoise is denser and less porous.
Stability:
• High heat can cause discoloration and surface damage. Chemicals, cosmetics, and even skin oils or perspiration can also discolor it.
Natural African turquoise (jasper)
Composition:
• A type of jasper, which is a form of chalcedony. It is composed mainly of silicon dioxide and may contain inclusions of other minerals like copper and iron, contributing to its mottled color palette.
Hardness:
• Ranges from 6.5 to 7 on the Mohs scale, making it harder and more durable than natural turquoise.
Stability:
• Avoid strong impacts, high falls, heat, and open flames, as these can cause damage. Prolonged water exposure can cause it to soften or disintegrate, leading to potential color fading and structural damage. It is also susceptible to damage from household chemicals.
Dyeing:
• Many African turquoise beads on the market have undergone a dyeing process to achieve their distinctive color. Genuine pieces are typically darker than real turquoise.
General handling and wearing
Remove During Activities:
• Take off both types of jewelry before engaging in activities that could expose them to harsh chemicals, water, or potential impacts. This includes tasks like swimming, showering, exercising, or cleaning.
Apply Cosmetics Last:
• Put on lotions, perfumes, hairspray, and makeup before wearing your jewelry. These chemicals can seep into porous turquoise or potentially damage dyed African turquoise.
Handle Gently:
• Both stones can chip or break with impacts. Handle your jewelry carefully.
Protect from Sun and Heat:
• Store both stones away from prolonged direct sunlight or high heat, which can cause discoloration or fading.
Check Settings:
• Regularly inspect your jewelry for any loose prongs or settings and have them repaired by a professional jeweler to avoid losing the stones.
Cleaning
Always use the gentlest cleaning method suitable for the material.
Avoid Harsh Chemicals:
• Never use commercial jewelry cleaners, ammonia, bleach, or any abrasive substances on either stone. These can damage the surface, alter the color, or affect dye treatments.
Wipe After Each Wear:
• Use a soft, lint-free cloth to gently wipe away oils, dust, and residues after each wear.
Warm Water and Mild Soap:
• Create a solution of warm water and a few drops of mild, alcohol-free dish soap.
Natural Turquoise:
• Gently wipe the jewelry with the solution. Avoid soaking it, as it's porous and can absorb water.
African Turquoise (Jasper):
• Wipe with a soft, damp cloth and mild soap. Avoid prolonged water exposure.
Soft Brush:
• A soft-bristled brush, like a baby toothbrush, can be used to gently clean around settings or in crevices. Be careful not to scratch the stone, especially with natural turquoise.
Rinse and Dry Thoroughly:
• Rinse the jewelry briefly and thoroughly under cool, running water to remove soap residue. Pat dry immediately with a clean, soft cloth or paper towel, ensuring no moisture remains. Allowing water to sit on the stone, particularly turquoise, can harm it.
No Ultrasonic or Steam Cleaners:
• Avoid these as they can damage both stones and potentially affect dyed materials.
Metal Components:
• If your jewelry has metal components like sterling silver, clean them according to their specific needs. Use a silver polishing cloth for sterling silver, being careful not to touch the stone. One source recommends making a paste of baking soda and water to clean tarnished silver, rubbing gently with a soft cloth and rinsing thoroughly, avoiding contact with the turquoise.
Storage
Cool, Dry, Dark Place:
• Store both types of jewelry in a cool, dry place away from direct sunlight, which can fade colors. Avoid storing them in damp places like bathrooms.
Separate Storage:
• Store each piece individually in a soft pouch or a lined compartment in a jewelry box to prevent scratching from harder gemstones or other jewelry pieces. The Natural Gemstone Company highlights that turquoise's Mohs scale position of 5-6 makes it susceptible to scratches.
Consider Anti-Tarnish:
• If the jewelry has metal components like sterling silver, consider storing it in an airtight bag or with anti-tarnish slips to prevent tarnishing.
By following these specific care instructions, you can help preserve the beauty and vibrant colors of your natural turquoise and African turquoise jewelry for many years to come.
