Gemstones You Shouldn’t Wear Every Day

Gemstones are not just about beauty; they also have different levels of durability. Some minerals are too soft or sensitive to withstand daily wear, exposure to water, or sunlight.

If you want your jewelry to last for years, it is essential to know which stones require extra care.

1. Opal – The Gem That Can “Dry Out”

Hardness: 5.5–6.5 on the Mohs scale

Why is it risky? Opal contains up to 20% water, making it vulnerable to drying out and sudden humidity changes. Over time, it can lose its luster or even develop microcracks.

To maintain its beauty, opal should be stored in a humid environment and kept away from direct sunlight or prolonged exposure to dry air.

Tip: Avoid wearing opal daily and store it properly to prevent dehydration.

2. Emerald – The Fragile Aristocrat

Hardness: 7.5–8 on the Mohs scale

Why is it risky? Emeralds almost always have inclusions and microfractures (jardin), making them highly prone to chipping upon impact. Despite their hardness, they are considered brittle due to internal flaws.

Because of their delicate nature, emeralds are often treated with oil to improve clarity, but this treatment can wear off over time, requiring re-oiling.

Tip: Do not clean emerald jewelry in ultrasonic cleaners and avoid wearing it during active activities.

3. Pearl – The Enemy of Perfume and Water

Hardness: 2.5–4 on the Mohs scale

Why is it risky? Pearl is one of the softest natural materials used in jewelry. It is easily scratched even by clothing or dust. Additionally, pearls are sensitive to acids, chemicals, and sweat, meaning perfume, cosmetics, and soap can gradually erode their surface.

Since pearls contain organic material, they require gentle handling and proper storage to prevent drying out or damage.

Tip: Pearls should be the last thing you put on and the first thing you take off. Avoid exposure to chemicals and store them separately from harder gemstones to prevent scratching.

4. Tanzanite – A Rare Beauty That Can’t Handle Impact

Hardness: 6–7 on the Mohs scale

Why is it risky? Although tanzanite may resemble sapphire, it is much softer and can fracture even from minor impacts. Additionally, it is often heat-treated, which makes the stone even more fragile.

Rings with tanzanite require extra care, as accidental knocks or rough handling can easily cause cracks or chips.

Tip: If you want to wear tanzanite in a ring, choose a protective setting to reduce the risk of damage.

5. Kunzite – A Stone That Fades in the Sun

Hardness: 6.5–7 on the Mohs scale

Why is it risky? Kunzite has a beautiful pink-lilac color, but one major drawback – it fades when exposed to sunlight for long periods. Over time, excessive UV exposure can cause the stone to lose its vibrancy.

For this reason, kunzite is best suited for evening jewelry rather than daily wear.

Tip: Avoid prolonged exposure to sunlight and store kunzite in a dark place when not in use.

6. Moonstone – Prone to Cracking

Hardness: 6–6.5 on the Mohs scale

Why is it risky? Moonstone has a layered structure, making it susceptible to cracking and chipping when exposed to impact. This is especially problematic in rings, which are more likely to encounter bumps and knocks.

Despite its mystical glow, moonstone requires careful handling to prevent fractures.

Tip: It is best to wear moonstone in pendants or earrings rather than rings, where the risk of damage is higher.

Which Gemstones Are Safe for Everyday Wear?

If you are looking for durable stones that can withstand daily wear, consider:

• Diamond (10/10 on the Mohs scale) – The hardest natural gemstone.

• Sapphire and ruby (9/10) – Nearly as tough as diamonds.

• Tourmaline (7.5/10) – Durable, but best worn in a protective setting.

Even the hardest gemstones require proper care to maintain their brilliance. Regular cleaning, proper storage, and avoiding exposure to harsh chemicals can significantly extend the life of your jewelry.

Understanding the characteristics of gemstones can help you make informed decisions and keep your jewelry in excellent condition for years to come.
