How to Tell if a Gemstone Has Been Damaged
Gemstones are nature’s treasures—formed deep within the earth over millions of years and cherished for their beauty and brilliance. But even the toughest stones can suffer damage from impact, heat, or chemicals. A scratch, a dull surface, or a change in color can all signal that something isn’t right. Here’s a guide to help you determine whether your gemstone has been damaged—and how to protect it for years to come.
Begin with a Careful Visual Inspection
Start by examining your gemstone in bright, natural light. A jeweler’s loupe or magnifying glass can help you spot small imperfections that are hard to see with the naked eye.
- Scratches and abrasions: Diamonds and sapphires are extremely hard, but they can still scratch other stones—or even each other—if stored together. Softer gems like opals, turquoise, and pearls are especially vulnerable.
- Chips and cracks: Look closely along the edges and across the surface for tiny chips or fractures. These can weaken the stone and make it more likely to break.
- Dull or uneven surface: If your gemstone once had a brilliant shine but now looks cloudy or matte, it may have been worn down or exposed to harsh chemicals.
Hold the stone up to the light—damage often becomes more visible when light passes through it.
Check Color and Clarity
A gemstone’s color and clarity reveal a lot about its condition. Changes in hue or transparency can indicate exposure to sunlight, heat, or cleaning agents.
- Color fading: Some gems, such as amethyst and topaz, can lose their color if left in direct sunlight for long periods.
- Cloudiness: A gemstone that looks milky or hazy may have developed microscopic fractures or absorbed moisture.
- Spots or stains: These can appear if the stone has reacted with perfume, lotion, or household cleaners.
If possible, compare your gemstone to older photos of the jewelry to see if its color or brightness has changed over time.
Examine the Setting and Surroundings
Sometimes the problem isn’t with the gemstone itself but with the setting that holds it. A loose or bent setting can make the stone unstable—or even cause it to fall out.
- Gently nudge the stone with your fingertip. If it moves, it’s time to have it checked by a jeweler.
- Look for discoloration or corrosion in the metal around the stone, which can affect both appearance and security.
A damaged setting can also create reflections that make the gemstone appear scratched or dull when it’s actually fine.
Seek a Professional Evaluation
If you’re uncertain about what you’re seeing, take your gemstone to a professional jeweler or gemologist. They have specialized tools to determine whether the damage is superficial or structural.
Experts can also advise whether the stone can be polished or repaired. Some surface blemishes can be removed, but deeper cracks are often permanent.

Prevent Future Damage
The best way to preserve your gemstone’s beauty is through proper care and prevention:
- Store each piece of jewelry separately in a soft pouch or lined box.
- Remove jewelry before cleaning, exercising, or showering.
- Keep gemstones away from perfume, hairspray, and cleaning products.
- Have your jewelry inspected regularly, especially if you wear it often.
With a little attention and care, your gemstones can retain their sparkle and value for generations—becoming timeless keepsakes that tell their own stories.
