The soft fire of white opals accompanies the cosmic color display of black opal creation, which draws people toward their unmistakable allure. Great beauty requires those who possess it to bear important duties. Opals are delicate. And yes, opals can crack.

Many gemstone fanatics and collectors wonder about the cause of opal cracking because these gems naturally break easily. The reasons behind opals' susceptibility to cracking stem from how they interact with their surroundings, together with their structural make-up. But worry not. Proper attention, along with appropriate knowledge, will help your opal stay magnificent and untarnished following the day you first owned it.

This article examines what causes opals to crack while also providing beneficial advice to protect these gemstones.

The Science Behind Opals: What Makes Them Fragile?

A complete examination below the surface will reveal the causes of opal stone cracking.

As opposed to harder gems such as sapphires and rubies, opals remain non-crystalline. The mineral formation of hydrated silica contains between 0 and 20 percent water, which integrally exists in its structure. The water content within opals makes them highly sensitive to modifications in their environment. The water content of opals reaches between 3% and 10%, which creates their susceptibility to temperature fluctuations and drying conditions.

The water content in opals enables their brilliant color transformation, also known as "play-of-color," although it renders them particularly at risk of the deterioration process "crazing." Fine surface cracks known as crazing will form in stones because of drying or exposure to severe conditions.

Common Reasons Opals Crack

These factors below lead to the breaking of opals:

1. Loss of Moisture

Geological time combined with very arid storage conditions leads opals to become dehydrated and initiate cracking patterns. Excessive water loss results in structure deformation, which forms surface cracks on the opal stone.

2. Sudden Temperature Changes

Opals don’t like surprises. The sudden movement between warm and cool environments creates internal stress that results in stone fractures.

3. Mechanical Shock

Opals exist in the mid-range of the hardness scale between 5.5 and 6.5 on the Mohs scale. The structure of your opal can break after one momentary impact or forceful blow.

4. Poor Setting or Pressure

The wrong placement of opal jewelry results in setting pressure, which gradually causes the stone to break. The same risk exists for doublets and triplets since they consist of opal slices glued to backings or under protective tops.

Tips to Keep Your Opal Safe and Stunning

The good news? Keeping proper care measures in place ensures that opals can be your permanent friends for life. The following list offers step-by-step instructions to maintain your opal’s structural integrity:

1. Avoid Extreme Temperatures

Wear opals cautiously when temperature shifts are likely to occur because saunas and hot tubs, as well as severe cold outdoor events, can damage the stone. Maintain a safe distance from heaters as well as windowsills.

2. Hydrate Your Stone (Carefully)

The only safe water contact for an opal should be minimal but you can keep it safe from drying out through exposure to low-level moisture. You should store your opal together with a moistened cotton ball inside an airtight plastic bag to retain moisture in hot and dry climate zones.

Natural solid opals remain unaffected by water because the other versions that use glues, such as doublets or triplets, might delaminate when exposed to water.

3. Use Gentle Cleaning Methods

Ultrasonic cleaners should never be used and avoid nonbenign chemical substances. Wipe your opal using a soft and slight damp cloth. In order to clean rings with intricate designs you should use mild soap combined with lukewarm water.

4. Opt for Protective Settings

The choice of bezel settings should replace prongs during the setting process for opals featured in rings and bracelets because bezel settings provide superior protection against bumps. Extra support and protection come from structures that envelop the gemstone from all sides.

5. Don’t Store Opals in Dry Air

Living in an arid environment requires proper storage of opals inside safes by controlling humidity when you plan to keep them there for an extended period. A dry environment will steal the vital moisture from these gemstones.

How Do You Know If Your Opal is About to Crack?

Prior to breaking your opal, sometimes displays these subtle warning signs:

• A sudden change in clarity or a dull appearance
• Hairline microfractures known as crazing will form beneath the surface of the stone.
• Unusual changes in color or play-of-color pattern

Take the opal out of regular use promptly when you see such warning signs and consult with a gemologist or jeweler.

Choosing the Right Opal: Solid, Doublet, or Triplet?

Knowledge about the type of opal you have will guide your proper maintenance.

• Natural Solid Opals comprise a complete untamed piece of opal which exhibits both the highest value and survival capability.
• The construction of doublets includes attaching a thin piece of opal to a supporting surface. Water damage affects these stones because they have lower costs compared to others.
• The opal slice in triplets receives additional defensive protection utilizing a quartz or glass layer. Protective elements exist in these items, but delamination will develop as time progresses.

Other Delicate Beauties: Moonstone and Larimar

Many types of gemstones aside from opals require caring handling. Two additional gemstones join opals in this list of delicate rocks: Moonstone and Larimar exist near Mohs scale score 6. Similar care principles should be applied to both gems and minerals since rough handling should be avoided while storage and temperature exposure need proper attention.
