How to identify a real aquamarine stone

Aquamarine Bracelet

Knowing how to differentiate between real and fake gemstones prevents you from getting conned by unscrupulous jewelry sellers. Here’s how to identify a real aquamarine stone. 

Check the clarity

Hold your gem against bright light and observe it from various angles. If you notice any eye-visible inclusions, the stone could be a fake. High-quality aquamarines are often clear, eye-clean, and transparent, meaning they don’t have flaws to the naked eye. 

Inspect the color 

Aquamarine stones are pleochroic in nature, meaning they reveal different hues when examined from different angles. So, if your gem appears to have only one color when viewed from various sides, it might be a fake.

Search for bubbles

Place your aquamarine under a bright light and view it through a 10x jeweler’s loupe. If you notice tiny bubbles within the stone’s structure, it might be a fake.

How to care for aquamarine jewelry

Taking good care of your gemstone will ensure it stays brilliant and beautiful for a long time. Here are a few care tips for your aquamarine jewelry: 

Clean your gems

Clean your aquamarine regularly, especially if you wear it often. Soak your jewelry in warm soapy water for about five minutes. 

Then use a soft-bristled toothbrush to clean the stone. Rinse it under warm water to get rid of the excess soap.

💡 Take Note: Use about one or two drops of mild dishwashing soap in a small bowl of warm water. Soap with harsh chemicals will discolor your gemstone.

Store in a cool place

When you’re not wearing your jewelry, store it in a cool, dry place. Aquamarine is sensitive and may fade when overexposed to heat.

Store it carefully

While aquamarine is a relatively hard gemstone resistant to scratches. It can scratch other stones, so it’s best to store it separately. Wrap it in a soft cotton cloth or keep it in a velvet-lined jewelry box. This storage also prevents it from chipping and getting dusty.

Take it off when doing strenuous activity

Take off your jewelry when doing strenuous activities like exercising or gardening. The stone is brittle and will easily break when struck.

Avoid contact with harsh chemicals

Avoid contact between your aquamarine and cleaning agents like household cleaners or cosmetics like shampoo. They contain harsh components like bleach, chlorine, and alcohol, which can discolor and fracture the gem.
