Check Diamond At Home

Diamonds are one of the most precious and valuable gemstones in the world. They are admired for their beauty, durability, and rarity. However, not everyone has the luxury of being able to take their diamond to a professional to be checked regularly. That’s why it’s important to learn how to check your diamond at home.

In this article, we’ll discuss the different methods for checking the quality and authenticity of a diamond at home, including using a loupe, conducting a water test, and performing the breath test.

Check Diamond At Home

  • Using a Loupe

A loupe is a small magnifying glass that jewelers use to examine the details of a diamond. By using a loupe, you can look for any visible inclusions or blemishes in the diamond. Inclusions are internal flaws that can affect the diamond’s clarity, while blemishes are external flaws that can affect its appearance.

To use a loupe, follow these steps:

  1. Hold the diamond by its girdle (the thin edge that runs around the circumference of the diamond) with a pair of tweezers.
  2. Hold the loupe up to your eye and bring the diamond close to it.
  3. Look at the diamond through the loupe and examine it for any inclusions or blemishes.
  4. Rotate the diamond and examine it from different angles to see if there are any flaws that are not visible from one angle.

  • Conducting a Water Test

The water test is a simple and effective way to check whether a diamond is real or fake. The principle behind this test is that a real diamond has a high density and will sink in water, while a fake diamond will float.

To conduct a water test, follow these steps:

  1. Fill a glass with water.
  2. Drop the diamond into the glass of water.
  3. Observe whether the diamond sinks or floats.
  4. If the diamond sinks, it is real. If it floats, it is fake.

  • Performing the Breath Test

The breath test is another simple test you can perform at home to check the authenticity of a diamond. The principle behind this test is that a real diamond is a good conductor of heat and will disperse the heat from your breath quickly, while a fake diamond will retain the heat and fog up.

To perform the breath test, follow these steps:

  1. Hold the diamond between your index finger and thumb.
  2. Breathe on the diamond to fog it up.
  3. Observe how quickly the fog clears.
  4. If the fog clears immediately, it is a real diamond. If it takes a few seconds to clear, it is a fake diamond.

Tips for Buying a Quality Diamond

Buying a diamond can be an exciting and rewarding experience. Diamonds are a symbol of love and commitment, and they are also a valuable investment. However, with so many options available, it can be overwhelming to know where to start. Here are some tips for buying a quality diamond.

  1. Learn the 4 Cs

The 4 Cs of diamond grading are color, clarity, cut, and carat weight. These characteristics determine the value of the diamond. The color of a diamond ranges from colorless to yellow, with colorless diamonds being the most valuable. Clarity refers to the number of inclusions or blemishes in the diamond. A higher clarity grade means fewer inclusions and a more valuable diamond. Cut refers to the quality of the diamond’s cut, which affects its brilliance and sparkle. Carat weight refers to the size of the diamond. It’s essential to understand these 4 Cs when buying a diamond to ensure you get the best value for your money.

  1. Set a Budget

Diamonds can vary greatly in price, and it’s important to set a budget before starting your search. Knowing your budget will help you narrow down your options and ensure that you are only looking at diamonds that are within your price range.

  1. Choose a Reputable Jeweler

When buying a diamond, it’s essential to choose a reputable jeweler. Look for a jeweler with a good reputation, who has been in business for a while, and who has positive reviews from previous customers. A reputable jeweler will provide you with a certificate of authenticity for the diamond and will also be able to answer any questions you have about the diamond’s quality and value.

  1. Consider the Setting

The setting of a diamond can also affect its overall appearance and value. A well-crafted setting can enhance the beauty of the diamond and make it appear larger. It’s important to consider the setting when buying a diamond, and to choose a setting that will showcase the diamond’s best qualities.

  1. Trust Your Instincts

Finally, when buying a diamond, it’s essential to trust your instincts. If something doesn’t feel right or if you’re not sure about the quality of the diamond, it’s okay to walk away. Don’t be pressured into buying a diamond that you’re not completely satisfied with.

Buying a quality diamond requires research, a budget, a reputable jeweler, consideration of the setting, and trusting your instincts. By following these tips, you can ensure that you make an informed decision and find the perfect diamond for your needs.


In conclusion, checking the quality and authenticity of a diamond at home is easy and can be done using a loupe, water test, or breath test. However, if you’re unsure about the quality or authenticity of your diamond, it’s always best to consult a professional. A professional jeweler can provide you with a more detailed assessment of your diamond’s value and quality, as well as help you with any repairs or cleaning.
