Taking proper care of your gemstones ensures their lasting beauty and brilliance. This involves understanding their unique properties, regular gentle cleaning, and safe storage practices.
General Gemstone Care Principles
Maintaining the beauty and integrity of your gemstones is simpler than you might think. Adhering to a few fundamental principles can significantly extend their lifespan and sparkle.
Regular Cleaning
Most gemstones benefit from regular, gentle cleaning to remove oils, dirt, and residue from daily wear.
- Warm Soapy Water Method: The vast majority of gemstones can be safely cleaned using a simple solution. Mix a small amount of mild detergent (such as unscented washing-up liquid) with warm water in a bowl. Crucially, ensure the water is not too hot, as sudden temperature changes can harm some gems.
- Gentle Scrubbing: Use a soft brush (like a soft-bristled toothbrush) to carefully clean around the gemstone and its setting, reaching crevices where dirt can accumulate.
- Rinse Thoroughly: After scrubbing, rinse the gemstone under cool, running water to remove all soap residue.
- Dry Carefully: Pat the gemstone dry with a soft, lint-free cloth. For intricate pieces, allow them to air dry completely before storing.

Safe Storage
Proper storage prevents scratches and damage, preserving your gemstones.
- Individual Compartments: Store each gemstone or piece of jewelry separately in a soft pouch (like velvet or flannel) or a jewelry box with fabric-lined compartments. This prevents harder gems from scratching softer ones.
- Away from Sunlight and Heat: Prolonged exposure to direct sunlight or extreme heat can fade or damage some gemstones, especially those that are heat-treated or organic.
- Avoid Clutter: Do not pile jewelry together, as this increases the risk of tangles, scratches, and breakage.
Avoiding Damage
Protecting your gemstones from potential harm is crucial for their longevity.
- Chemical Exposure: Always remove gemstone jewelry before using household cleaning products, applying lotions, perfumes, hairspray, or engaging in activities where they might come into contact with harsh chemicals. These substances can dull the gem's luster, etch its surface, or even cause discoloration.
- Impact and Abrasion: Gemstones, even hard ones like diamonds, can chip or break if struck against a hard surface. Remove jewelry before strenuous activities, gardening, or sports.
- Temperature Extremes: Avoid exposing gemstones to sudden and drastic temperature changes. This is particularly important for gems like opals, which can crack or craze.
- Ultrasonic and Steam Cleaners: While effective for some robust gems (like diamonds and sapphires), ultrasonic cleaners can damage others (e.g., pearls, opals, emeralds, heat-treated gems) by loosening settings or causing internal fractures. Always check if a gem is safe for these methods.
Specific Gemstone Care Considerations
While general rules apply, many gemstones have unique characteristics that demand specific care. Understanding these differences is key to their longevity.
Mohs Hardness Scale
The Mohs Hardness Scale measures a gemstone's resistance to scratching. Knowing a gem's hardness helps determine its durability and appropriate care.
- Hard Gemstones (7 and above): Diamonds (10), Rubies (9), Sapphires (9), and Topaz (8) are durable and generally tolerant of the warm soapy water method. However, they can still chip or fracture with a hard impact.
- Softer Gemstones (Below 7): Pearls (2.5-4.5), Opals (5.5-6.5), Turquoise (5-6), Amber (2-2.5), and Lapis Lazuli (5-6) are more susceptible to scratches, abrasions, and chemical damage. They often require specialized, gentler cleaning and handling.
Porous Gemstones
Some gemstones are porous and can absorb chemicals, oils, or even water, leading to discoloration or damage.
- Examples: Turquoise, Opal, Pearl, Amber, and Lapis Lazuli.
- Care: Avoid prolonged water exposure, harsh chemicals, and even body lotions. Clean with a soft, damp cloth only, and dry immediately.
Treated Gemstones
Many gemstones undergo treatments to enhance their color or clarity. These treatments can affect how they should be cared for.
- Heat Treatment: Common for rubies and sapphires. Generally stable, but extreme temperature changes should still be avoided.
- Dyeing: Often applied to jade, turquoise, and coral. Dyes can fade or leach out with harsh cleaners or prolonged water exposure.
- Fracture Filling: Used in emeralds, rubies, and diamonds. The filling material can be damaged by heat, chemicals, or ultrasonic cleaners.
- Care: When in doubt, assume a gemstone is treated and opt for the gentlest cleaning method – warm water and mild soap, or just a soft, damp cloth.
Quick Care Guide for Common Gemstones
| Gemstone | Mohs Hardness | General Care Tips | Avoid |
|---|---|---|---|
| Diamond | 10 | Warm soapy water, soft brush. Professional cleaning recommended periodically. | Harsh chemicals, extreme impact. |
| Ruby/Sapphire | 9 | Warm soapy water, soft brush. Generally durable. | Strong acids, extreme heat changes (especially for treated gems). |
| Emerald | 7.5-8 | Mild soapy water, soft cloth. Protect from impact. | Ultrasonic/steam cleaners, harsh chemicals, sudden temperature changes. Often fracture-filled. |
| Pearl | 2.5-4.5 | Wipe with soft, damp cloth after wear. Store separately. | Water immersion, chemicals, perfumes, acids, ultrasonic cleaners. |
| Opal | 5.5-6.5 | Wipe with soft, damp cloth. Protect from dryness, impact, sudden temperature changes. | Dehydration, harsh chemicals, ultrasonic cleaners, extreme heat/cold. |
| Amethyst/Citrine | 7 | Warm soapy water, soft brush. Protect from prolonged sun exposure (can cause fading). | Extreme heat (can fade color), harsh chemicals. |
| Turquoise | 5-6 | Wipe with soft, dry cloth. Avoid water and chemicals. | Water, oils, lotions, perfumes, harsh chemicals, ultrasonic cleaners. Highly porous. |
When to Seek Professional Help
For valuable or particularly delicate gemstone jewelry, professional care can be invaluable.
- Deep Cleaning: Jewelers have specialized equipment and expertise for thorough, safe cleaning that might not be possible at home.
- Repairs: For loose settings, damaged prongs, or broken pieces, a professional can perform necessary repairs without risking further damage to the gem.
- Inspection: Regular professional inspections can identify potential issues, such as weakened settings or minor damage, before they become serious problems.
By following these guidelines, you can ensure your gemstones retain their beauty and value for generations.
