Cleaning Tips for Diamonds, Sapphires, and Rubies

Proper cleaning is essential for maintaining the brilliance and longevity of gemstones. Regular care prevents the buildup of dirt and oils, preserving their natural sparkle. This guide focuses on diamonds, sapphires, and rubies—three of the most treasured gemstones. Each has unique properties and requires specific cleaning methods to ensure they remain as stunning as the day they were acquired. By following appropriate cleaning practices, you can protect your precious stones and enhance their beauty for years to come.

Understanding Your Gemstones

Diamonds: Characteristics and General Care Needs

Characteristics:

  • Hardness: Diamonds rank 10 on the Mohs scale, making them the hardest natural material. This exceptional hardness ensures that diamonds are highly resistant to scratches.
  • Clarity and Brilliance: Diamonds are known for their unmatched sparkle and clarity. The high refractive index contributes to their brilliance, reflecting light in dazzling ways.
  • Durability: Despite their hardness, diamonds can attract dirt, oil, and residue, which can dull their shine over time.

General Care Needs:

  • Cleaning: Regular cleaning is vital to maintain the diamond’s brilliance. Use a soft brush with mild soap and warm water. Gently scrub the diamond to remove any dirt and oil, then rinse thoroughly and pat dry with a lint-free cloth.
  • Avoid: Avoid using harsh chemicals, which can damage the diamond. Do not expose diamonds to abrasive materials that could scratch the surface.
  • Storage: Store diamonds separately in a soft cloth or a lined jewelry box to prevent them from scratching other gemstones or each other.

Sapphires: Characteristics and General Care Needs

Characteristics:

  • Hardness: Sapphires are the second hardest gemstones, scoring 9 on the Mohs scale. This makes them durable but not immune to damage.
  • Color Variety: Sapphires are available in a range of colors, including blue, pink, yellow, and more. The most sought-after sapphires are deep blue.
  • Durability: While they are highly durable, sapphires can be sensitive to certain chemicals and high temperatures.

General Care Needs:

  • Cleaning: Clean sapphires with mild soap, warm water, and a soft brush. Gently scrub to remove any dirt, then rinse and dry with a soft cloth. Occasional use of ultrasonic cleaners is acceptable but should be done with caution.
  • Avoid: Avoid ammonia-based cleaners as they can harm the gemstone. Refrain from exposing sapphires to extreme temperature changes and harsh chemicals.
  • Storage: Store sapphires individually in a soft cloth or padded compartment to prevent them from scratching other jewelry pieces.

Rubies: Characteristics and General Care Needs

Characteristics:

  • Hardness: Rubies, like sapphires, belong to the corundum family and also score 9 on the Mohs scale, making them very hard and durable.
  • Color: Rubies are cherished for their vibrant red color, ranging from pinkish-red to a deep, rich crimson.
  • Durability: While rubies are highly durable, they require specific care to maintain their stunning appearance.

General Care Needs:

  • Cleaning: Clean rubies with mild soap and warm water using a soft brush. Gently scrub to remove any dirt or oil, rinse well, and dry with a soft cloth. Avoid frequent use of ultrasonic cleaners.
  • Avoid: Harsh chemicals and exposure to extreme temperature changes can damage rubies. Always use gentle cleaning methods to preserve their color and clarity.
  • Storage: Store rubies in a separate compartment or wrap them in a soft cloth to protect them from scratches and damage from other jewelry.


Common Cleaning Solutions and Their Safety

Mild Soap and Water: Universal Solution for Diamonds, Sapphires, and Rubies

Description: Mild soap and water is the safest and most effective cleaning solution for diamonds, sapphires, and rubies. It gently removes dirt and oils without damaging the gemstones. 

Usage: Mix a small amount of mild soap with warm water. Soak the gemstone in the solution for a few minutes, then use a soft brush to clean. Rinse thoroughly with clean water and dry with a soft cloth. 

Safety: This method is safe for all three gemstones and can be used regularly without any risk of damage.

Ammonia-Based Cleaners: Suitable for Diamonds, But Caution for Sapphires and Rubies

Description: Ammonia-based cleaners are effective for removing tough grime from diamonds, thanks to their chemical composition. 

Usage: Mix one part ammonia with six parts water. Soak the diamond in the solution for up to 10 minutes, then gently brush and rinse with water. 

Safety: While safe for diamonds, ammonia-based cleaners should be used with caution on sapphires and avoided on rubies, as they can cause damage or discoloration.

Ultrasonic Cleaners: When to Use and When to Avoid

Description: Ultrasonic cleaners use high-frequency sound waves to create bubbles that remove dirt from jewelry. 

Usage: Place the jewelry in the cleaner with the appropriate cleaning solution and run the device as instructed. 

Safety: Ultrasonic cleaners are generally safe for diamonds but should be used with caution for sapphires. They are not recommended for rubies, as the vibrations can cause internal damage or worsen existing fractures.

Steam Cleaners: Safe for Diamonds but Can Be Risky for Sapphires and Rubies

Description: Steam cleaners use high-pressure steam to clean gemstones by blasting away dirt and grime. 

Usage: Hold the gemstone with tweezers and direct the steam at it for a few seconds. 

Safety: Steam cleaners are safe for diamonds, but they can be risky for sapphires and rubies. The high temperature and pressure can cause these gemstones to crack or become damaged, so it’s best to avoid using steam cleaners on them.

Specific Cleaning Guidelines

Diamonds: Safe Practices and Frequency

Safe Practices:

  • Cleaning: To keep your diamonds sparkling, regularly clean them with a soft brush, mild soap, and warm water. Soak the diamond in the solution for a few minutes, then gently scrub all sides, especially around the setting, to remove dirt and oil buildup. Rinse thoroughly with warm water and dry with a lint-free cloth.
  • Avoid: Steer clear of harsh chemicals like bleach and abrasive materials that can scratch the diamond or damage its setting. Additionally, avoid exposing diamonds to sudden temperature changes, which can cause fractures.
  • Storage: Store diamonds separately in a fabric-lined jewelry box or soft cloth pouch to prevent them from scratching other pieces of jewelry or each other.

Frequency:

  • Clean your diamonds once a month to maintain their brilliance. For heavily worn pieces, consider more frequent cleanings or professional cleanings to ensure their continued sparkle.

Sapphires: Gentle Methods and What to Avoid

Gentle Methods:

  • Cleaning: Clean sapphires by mixing a few drops of mild soap with warm water. Soak the sapphire for five to ten minutes, then use a soft brush to gently clean the stone, paying attention to the areas around the setting. Rinse thoroughly with warm water and dry with a soft, lint-free cloth.
  • Occasional Use: Ultrasonic cleaners can be used occasionally but only if the sapphire is free from fractures and inclusions that could be exacerbated by the ultrasonic waves.

What to Avoid:

  • Avoid: Ammonia-based cleaners and other harsh chemicals, as they can damage the surface of the sapphire. Avoid frequent use of ultrasonic cleaners, which can cause internal damage if used excessively.
  • Storage: Store sapphires separately in a padded compartment or wrap them in a soft cloth to protect them from scratches and contact with other harder gemstones.

Rubies: Best Practices and Precautions

Best Practices:

  • Cleaning: To clean rubies, use a solution of mild soap and warm water. Soak the ruby for a few minutes, then gently scrub with a soft brush, making sure to clean all sides and the setting. Rinse well with warm water and pat dry with a soft, lint-free cloth.
  • Avoid: While occasional use of ultrasonic cleaners is acceptable, avoid frequent use, as the vibrations can cause existing fractures to expand or create new ones.

Precautions:

  • Avoid: Exposure to harsh chemicals and extreme temperature changes, which can affect the ruby’s color and clarity. Never use bleach or other strong cleaning agents.
  • Storage: Store rubies in a separate compartment or wrap them in a soft cloth to prevent scratches and damage from other jewelry pieces. Rubies, like other gemstones, should be kept away from prolonged exposure to direct sunlight to avoid color fading.
