What can damage a Sapphire

Sapphires are renowned for their exquisite beauty, durability, and versatility. They are among the hardest natural gemstones, second only to diamonds on the Mohs scale of mineral hardness. This remarkable hardness has contributed to the sapphire’s popularity in jewelry and industrial applications. However, despite their remarkable resilience, sapphires are not invulnerable. Various factors and circumstances can potentially damage a sapphire, affecting both its appearance and structural integrity. In this comprehensive article, we will delve into the different aspects of what can damage a sapphire, exploring factors ranging from physical impacts and heat exposure to chemical interactions and poor maintenance practices.


1. Physical Impacts: The First Threat

One of the most immediate threats to a sapphire’s well-being is physical impact. Despite their hardness, sapphires can still be damaged by external forces, and this is especially true when they are used in jewelry. Even though sapphires rank high on the Mohs scale, they can still fracture, chip, or break when subjected to sharp blows or impacts. This risk is not limited to sapphires alone; it extends to the settings and surrounding materials in which the gemstone is placed. Here’s a closer look at how physical impacts can damage a sapphire.


1.1. Prone to Chipping and Cracking

Sapphires are incredibly hard, scoring a 9 on the Mohs scale, just one notch below diamonds. However, their hardness can sometimes be a double-edged sword. While their resistance to scratching is admirable, it makes them more susceptible to chipping and cracking upon sudden impacts. Sapphires, particularly when used in rings or bracelets, can come into contact with hard surfaces like countertops or floors, increasing the risk of damage. A strong blow can result in visible chips, cracks, or even the complete fracturing of the sapphire.

1.2. Vulnerable Settings

The setting of a sapphire in jewelry plays a critical role in its protection. Settings that leave the sapphire exposed or have inadequate prongs can subject the gemstone to damage from physical impacts. For instance, a protruding sapphire in a ring is more likely to come into contact with surfaces, increasing the chances of chipping or cracking. Similarly, prongs that are too thin or weak can fail to secure the sapphire adequately, leading to displacement or damage.

1.3. Wear and Tear

Wearing sapphire jewelry regularly can result in gradual wear and tear. Over time, minor surface scratches may accumulate, diminishing the gemstone’s brilliance and overall appeal. While these scratches may not always qualify as significant damage, they can affect the sapphire’s aesthetics and reduce its value.

2. Heat Exposure: A Silent Threat

Sapphires are known for their remarkable resistance to high temperatures, but extreme heat can still damage them under certain conditions. While sapphires can withstand high temperatures without melting or deforming, they are not entirely immune to the effects of heat. Heat can affect sapphires in various ways, primarily by altering their color and clarity.

2.1. Color Alteration

One of the significant ways heat exposure can damage a sapphire is by causing changes in its color. While sapphires are typically valued for their rich blue hues, they can come in a range of colors, including pink, yellow, and green. Heat treatment is a common practice in the gemstone industry to enhance the color of sapphires. However, exposing sapphires to excessive heat or sudden temperature changes can result in undesirable color shifts. This can lead to a reduction in the gemstone’s value and desirability, as the original, sought-after color is compromised.

2.2. Clarity Issues

High temperatures can also cause internal fractures or inclusions within the sapphire to expand or become more visible. This can result in a reduction in clarity, which is another critical factor in a sapphire’s value. Clarity refers to the presence or absence of internal flaws, and sapphires with fewer inclusions are generally considered more valuable. Heat-induced clarity issues can detract from the gemstone’s overall appeal and value.

2.3. Differential Expansion and Contraction

Sapphires can withstand high temperatures but may still be vulnerable to sudden temperature changes. If a sapphire is exposed to extreme heat and then rapidly cooled, it can experience differential expansion and contraction, which can lead to stress fractures or even shattering. This is especially true for sapphires with existing internal flaws or structural weaknesses.

3. Chemical Interactions: Hidden Dangers

While sapphires are generally resistant to chemical damage, they are not entirely impervious to certain substances and conditions. Chemical interactions can harm sapphires in various ways, from surface damage to long-term deterioration of their structure.

3.1. Exposure to Harsh Chemicals

One of the common ways sapphires can be damaged chemically is through exposure to harsh chemicals. Household chemicals, such as bleach, ammonia, or other strong cleaning agents, can potentially harm the gemstone’s surface. These chemicals can corrode metals in jewelry settings, which may lead to the gemstone becoming dislodged or damaged. Additionally, exposure to chemicals over time can cause a dulling of the sapphire’s polish and finish.

3.2. Reaction with Acids

Sapphires are resistant to most acids, but certain acids can still damage them. Hydrofluoric acid, for example, can etch the surface of a sapphire, leading to a loss of polish and luster. While exposure to such strong acids is relatively rare in everyday life, it’s essential to avoid contact with them to prevent potential damage to your sapphire jewelry.

3.3. Damage from Perspiration and Oils

Even the natural oils and acids found in human skin can, over time, affect the appearance of a sapphire. Wearing sapphire jewelry frequently can result in a buildup of oils and perspiration on the gemstone’s surface, causing it to lose its brilliance and shine. Regular cleaning and maintenance are necessary to prevent the gradual accumulation of these substances.

4. Poor Maintenance Practices: An Avoidable Threat

Maintenance plays a crucial role in preserving the beauty and integrity of sapphire jewelry. Neglecting proper care and cleaning can lead to avoidable damage and deterioration over time.

4.1. Inadequate Cleaning

One of the most common maintenance mistakes that can damage a sapphire is improper cleaning. Using abrasive materials or harsh chemicals to clean sapphire jewelry can scratch the gemstone’s surface and diminish its luster. It’s essential to use gentle cleaning methods, such as warm soapy water and a soft brush, to clean sapphires regularly. Additionally, using a soft cloth for drying and polishing can help maintain the gemstone’s shine.

4.2. Neglecting Prong Inspection

Regularly inspecting the prongs or settings of sapphire jewelry is crucial for preventing damage. Loose or damaged prongs can lead to the loss of the sapphire or, in some cases, cause it to become dislodged and fall out. Periodic inspections by a professional jeweler can help identify and rectify any issues before they result in significant damage.

4.3. Storing Jewelry Improperly

Improper storage of sapphire jewelry can also lead to damage. Storing jewelry in a disorganized manner can result in sapphires coming into contact with other hard materials, potentially leading to scratches or chips. It’s advisable to store sapphire jewelry in separate compartments or pouches to prevent such contact.

5. Conclusion: Protecting the Precious Sapphire

In conclusion, while sapphires are renowned for their hardness and durability, they are not impervious to damage. Various factors can threaten the appearance and structural integrity of sapphires, ranging from physical impacts and heat exposure to chemical interactions and poor maintenance practices. To protect the precious sapphire, it is essential to handle jewelry with care, avoid exposing it to extreme temperatures, be mindful of chemical exposure, and practice regular maintenance and cleaning. By following these guidelines, you can ensure that your sapphire jewelry remains a timeless and radiant treasure for generations to come.
