Why Your Diamond Looks Cloudy, Dull, or Hazy

Diamonds are known for their brilliant sparkle and natural radiance, but over time, you may notice that your diamond appears to look cloudy, milky, or hazy. Cloudiness in diamonds can be caused by a variety of factors, including internal flaws, external contaminants, and improper cleaning techniques. By gaining a deeper understanding of the causes of cloudy diamonds, you can take the necessary steps to restore their dazzling sparkle.

What Causes Cloudy Diamonds?

Clarity Issues or Inclusions

The primary reasons for a diamond appearing cloudy are issues with clarity and internal flaws known as inclusions. Inclusions in diamonds can be tiny crystals, feathers, or other mineral deposits that affect the transparency of the diamond. These issues are fundamentally connected to the nature and severity of the inclusions within the diamond, and the problem tends to become more pronounced as you move to lower clarity grades, such as SI1 and below.

Generally speaking, if a diamond with low clarity has inclusions like clouds or twinning wisps, which are listed as the factors determining its grade, extra caution is necessary. This is because the presence of these inclusions, along with pinpoints, can have a negative impact on the diamond's brilliance. Additionally, there are specific indicators in a grading report that can hint at a diamond's likelihood of being hazy. For instance, an inclusion plot showing an absence of plotted inclusions in a slightly included (SI) or included (I) diamond is one such sign that professionals look for. A prevalent misunderstanding about purchasing diamonds with lower clarity ratings is that their cloudy appearance is solely due to cloud inclusions. Contrary to this belief, other types of inclusions such as feathers or twinning wisps can also contribute to the chalky appearance, a fact that some people mistakenly overlook.

Examining diamonds with SI1 or SI2 clarity grades through videos or other concrete data is a requirement before purchasing. Vendors such as Blue Nile provide 360° HD videos, allowing you to see exactly what you are purchasing, and can determine if the diamond will look cloudy.

Dirt, Grime, and Oils on the Surface of Diamonds

A diamond ring's appearance may become cloudy due to the accumulation of external contaminants such as dirt, oil, and lotions on its surface. These substances can adhere to the diamond's facets and create a film that obstructs light from passing through the stone effectively. As a result, the diamond's brilliance and sparkle may be diminished, making the stone appear dull or cloudy. Regular cleaning maintenance is essential to remove these impurities and restore the diamond's natural luster.

Improper Cleaning Methods

Improper cleaning techniques can also contribute to diamond cloudiness, as harsh chemicals or abrasive materials can damage the diamond's surface and reduce its brilliance. Without proper care, even a high-quality diamond can appear lackluster due to these external factors.

How to Identify Cloudy Diamonds

Identifying whether a diamond is cloudy can be done through a few simple observations. Start by examining the diamond under bright, natural light. A cloudy diamond will lack the vibrant sparkle and brilliance that is characteristic of a clear diamond. Look for any haziness or milky appearance in the stone. If the diamond appears dull or lacks the fiery flashes of light, it may be cloudy. Another way to identify cloudiness is by observing the diamond from different angles. A clear diamond will reflect light evenly, while a cloudy diamond may have areas that appear darker or less brilliant.

How to Clean Cloudy Diamond Ring at Home

If you notice that your diamond has become cloudy, there are several methods you can try to restore its sparkle at home. Cleaning a diamond ring requires special care to ensure that both the diamond and the metal setting are properly cleaned.

  1. Soaking Method: One effective method is to create a gentle cleaning solution using warm water and mild dish soap. Make a solution with warm water (almost hot) and dish-washing soap. Soak your ring for about 20 to 40 minutes, gently brush the stone with a very soft toothbrush, and then rinse under warm running water. Then use a soft-bristled toothbrush to gently scrub away any dirt or oils. Rinse the diamond thoroughly with clean water and pat it dry with a soft cloth. Avoid using any harsh chemicals or abrasive materials, as these can further damage the diamond.
  2. Ultrasonic Cleaner for Cloudy Diamonds: An ultrasonic jewelry cleaner is the most convenient and effective method for cleaning cloudy diamonds at home and restoring their brilliant sparkle. Ultrasonic cleaning machines use high-frequency sound waves to create vibrations that gently dislodge dirt and grime from the diamond's surface. These electronic jewelry cleaning machines are a safe, fast, and effective way to deep clean your diamonds at home. To use an ultrasonic jewelry cleaner, simply fill the tank with a water and a drop of Dawn dish soap, place your diamond ring in the basket or tray, and turn on the machine. The sonic waves will create gentle vibrations that help to dislodge dirt and oils from the diamond's surface. After the cleaning process, rinse the diamond thoroughly with clean water and dry it with a soft cloth. The result? A brilliantly clean, sparkling diamond ring that shines as bright as the day you first wore it. 

It's important to note that certain metals, such as silver, may require different cleaning methods, so be sure to research the appropriate cleaning techniques for your specific ring.

Professional Diamond Cleaning Services

If you're unsure about cleaning your diamond ring yourself, or if the cloudiness persists despite your best efforts, it may be time to seek professional diamond cleaning services. Professional jewelers have specialized equipment and expertise to safely and effectively clean your diamond. They can identify any underlying issues that may be contributing to the cloudiness and provide appropriate solutions. When choosing a professional diamond cleaning service, be sure to research reputable jewelers in your area and inquire about their cleaning methods and the certifications they hold.

Many local jewelers offer complimentary professional ring cleaning if you purchase the ring from them. This is often the best choice, as the jeweler will already be familiar with the intricacies of your specific ring. We recommend scheduling regular professional cleaning services for your diamond ring about twice a year for optimal care.

How to Keep Your Diamond Clean and Prevent Cloudiness

Here are a few tips to help you maintain the brilliance of your diamonds:

  1. Regular Cleaning: Clean your diamond jewelry regularly to remove any dirt, oils, or lotions that can contribute to cloudiness. Use gentle cleaning methods and avoid harsh chemicals or abrasive materials.
  2. Proper Storage: Store your diamond jewelry in a soft pouch or jewelry box to protect it from dust, dirt, and scratches. Avoid storing diamonds together with other jewelry pieces that may cause friction and damage the stones.
  3. Avoid Chemical Exposure: Take off your diamond jewelry when using harsh cleaning chemicals, swimming in chlorinated pools, or applying beauty products such as hairspray or lotion. These substances can cause cloudiness and damage to the diamond.
  4. Professional Inspections: Have your diamond jewelry inspected by a professional jeweler at least once a year. They can check for any signs of damage or cloudiness and provide appropriate maintenance or repairs if needed.
