Can Opal Be in the Sun? The Truth About Opal and Sunlight

Opals are beautiful and mesmerizing gemstones, renowned for their captivating play of color. However, there's a common misconception surrounding opals and their exposure to sunlight. Many believe that opals should be kept away from the sun, fearing potential damage. But is this truly the case? Let's delve into the truth about opal and sunlight.

The Myth of Opal and Sun Damage

The belief that opals are susceptible to sun damage stems from the gemstone's unique structure. Opals are not a crystal, but rather a hydrated amorphous form of silica. This means they contain water within their structure, which can evaporate if exposed to excessive heat.

The concern is that dehydration might cause the opal to crack or become brittle. While it's true that some opals are more susceptible to dehydration than others, this doesn't necessarily translate to direct sun damage.

Understanding Opal Types and Sun Exposure

To understand the relationship between opals and sun, we need to consider the different types of opals:

1. Precious Opal: These are the most valuable opals, renowned for their brilliant and vibrant play of color. Precious opals contain a higher water content, making them potentially more vulnerable to dehydration. However, this doesn't mean they'll instantly crack in the sun.

2. Common Opal: These opals are less valuable and generally lack the vivid play of color found in precious opals. They have a lower water content and are less susceptible to dehydration.

3. Boulder Opal: These opals are embedded in a matrix of ironstone, which helps stabilize them and makes them less prone to dehydration.

The Impact of Sunlight on Opals

While prolonged exposure to extreme heat can indeed affect an opal's water content, the average amount of sunlight most people encounter won't pose a significant threat. It's important to note that:

  • Direct sunlight can cause the opal to warm up, which can lead to slight dehydration.
  • The intensity and duration of sunlight exposure play a significant role.
  • The opal's individual characteristics (such as its water content and cut) also influence its susceptibility to dehydration.

Protecting Your Opal from Potential Damage

While opals can tolerate a reasonable amount of sunlight, it's always wise to take precautions, especially with precious opals. Here are some tips for protecting your opal:

  • Avoid prolonged exposure to direct sunlight: Limit the amount of time your opal spends in direct sunlight, particularly during the hottest parts of the day.
  • Store opals in cool, dry places: A jewelry box or drawer will offer adequate protection.
  • Keep opals away from heat sources: Avoid placing your opal near radiators, heaters, or fireplaces.
  • Avoid extreme temperature changes: Rapid changes in temperature can stress the opal and increase the risk of cracking.

Conclusion: Can Opal Be in the Sun?

The answer is yes, opals can be in the sun, but it's best to exercise caution. While the myth of opals being permanently damaged by sunlight is exaggerated, prolonged exposure to excessive heat can potentially affect their water content. By understanding the nuances of opal types and following simple precautions, you can ensure your beloved opal remains beautiful and vibrant for years to come.
