Gem Treatments, Enhancements, and Natural Gemstone Differences

When you hear the term ‘natural’ in the description of a gemstone, it’s not merely intended to be a simple descriptor, it’s more. Many consider it a badge of honor.

It signifies purity, rarity, and a connection to the earth, a gem that’s unaltered by human intervention. But to dig deeper (so to speak), what does the term ‘natural’ truly mean when determining the value of that gemstone you’re considering as a potential addition to your collection?

Is it merely a term used to differentiate from synthetic gemstones, or does it hold a deeper significance?

When I say ‘natural’, I am referring to gemstones that have been formed over millions of years under natural geological processes. These gemstones are mined from the earth, cut, and polished to reveal their inherent beauty.

Unlike their synthetic counterparts, natural gemstones are not created in a lab. They are a product of Mother Nature’s organic artistry, each one unique in its formation, color, and inclusions from the very earth that gave birth to it.

Going even deeper, the term ‘natural’ extends beyond the process of formation. It encompasses the color variations that occur naturally within these gemstones, adding to their allure and mystique. From their origination within mines and quarries to the jewelers’ worktable.

From the spectacular garnet to the radiant ruby, the color of a natural gemstone is a direct result of its chemical composition and the conditions under which it was formed.

But how do natural gemstones differ from their enhanced counterparts?

In this article, I will delve into the intricacies of natural gemstones, exploring their color variations, discussing the pros and cons of gemstone enhancements, and shedding light on what ‘natural’ truly means for a gemstone.

Whether you’re a seasoned collector or a novice enthusiast, join me on a fascinating journey into the world of gemstones and the enhancement secrets of the jewelry industry.

Gemstone Treatments And Enhancements: Natural vs Enhanced

Your understanding of the difference between natural and enhanced gemstones not only helps in appreciating the inherent beauty of these precious stones but also aids in making informed decisions when purchasing or collecting them.

Natural gemstones, as I mentioned earlier, are formed over millions of years under natural geological processes. They are mined from the earth, cut, and polished, with no additional treatments to enhance their color or clarity.

The beauty of a natural gemstone lies in its raw, unaltered state, making each one a unique piece of jewelry showcasing nature’s art.

On the other hand, enhanced gemstones are natural gemstones that have undergone treatments to improve their appearance. This type of treatment can range from a high-temperature heating process, which is used to intensify or change the color of the gemstone, to fracture filling, which improves the clarity of the gemstone.

While these gemstone enhancements can significantly improve the gemstone’s aesthetic appeal, they can also affect its value and durability.

The key lies in understanding the characteristics of both types and knowing what to look for. For instance, natural gemstones often have inclusions or flaws, which are considered ‘birthmarks’ of the stone. These inclusions can be a telltale sign of a gemstone’s natural origin. Enhanced gemstones, however, often appear ‘too perfect’, with their inclusions removed or made less visible through treatments.

Another fascinating aspect of natural gemstones is color variation. Unlike synthetic gemstones, which often have uniform colors, natural gemstones exhibit a wide range of colors, even within the same type of gemstone.

This diversity in color not only adds to their visual appeal but also contributes to their uniqueness and desirability as popular gemstones.

But what causes these color variations in natural gemstones? Again, the answer lies in their formation process. Natural gemstones, formed over millions of years under natural geological processes, are exposed to various elements and conditions that play a major role in the ultimate color of untreated gemstones.

So, how can you distinguish between natural and enhanced gemstones?

For instance, the presence of certain trace elements can impart specific colors to the gemstones. Take the example of precious gemstones such as sapphires. Pure corundum, the mineral from which sapphires are formed, is colorless.

However, when small amounts of iron and titanium are present during its formation, the corundum takes on a blue color, resulting in a blue sapphire. Similarly, the presence of chromium results in a pink sapphire.

Another factor that can influence the color of a gemstone is its radiation exposure. Some gemstones, like smoky quartz and amethyst, owe their color to the organic process originating from the natural radiation and radioactive materials in the earth itself.

Even still, it’s also worth noting that the color of a natural gemstone can change over time due to prolonged exposure to sunlight or heat. This is the case with gemstones like rose quartz that undergo minor changes in their atomic structure based on the way light shines through the gemstone if left out in the sun for too long.

Some gemstones, like amethyst and rose quartz, can fade if exposed to strong sunlight for an extended period. On the other hand, some gemstones, like zircon and kunzite, can darken when exposed to heat.

These beautiful (and fascinating) color variations serve as a reminder of the gemstone’s journey from the earth to our hands, with each color telling a bit of the unique story and reference of its formation and evolution.

Pros and Cons of Gemstone Enhancement

While the allure of natural gemstones lies in their raw, unaltered state, enhancement techniques have been used for centuries to improve the appearance of gemstones.

These techniques can intensify or change the color of the gemstones, improve their clarity, or even create special effects. However, like any other treatment process, gemstone enhancement comes with its own set of pros and cons.

One of the main advantages of gemstone enhancement is that it can significantly improve the aesthetic appeal of the gemstones.

Techniques like traditional heat treatment can intensify the color of the gemstones, making them more attractive to the eye. At the same time, fracture filling can improve the clarity of the gemstones, making them appear more flawless.

Another advantage of gemstone enhancement is that it can increase the availability of certain types of gemstones. For instance, natural blue topaz is extremely rare, and because of this very fact, they are often quite expensive.

Alternatively, and quite contrary to this, heat and irradiation treatment of colorless topaz can enhance the stone, transforming it into blue topaz, and as a result, making it more affordable and accessible to broader audiences.

On the flip side, one of the main disadvantages of gemstone enhancement is that it can negatively affect the value of a gemstone.

Natural gemstones–especially those with high-quality color and clarity–are rare and hence, more valuable. But when these same gemstones undergo enhancement, their value can decrease, depending on the type and extent of the treatment.

Another disadvantage is that some of these enhancement techniques can affect the durability and life of the gemstone. For instance, fracture-filled gemstones can be more susceptible to damage when exposed to subsequent heat treatment or harsh chemicals.

Because of this, enhanced gemstones often require special care and maintenance compared to their more resilient natural counterparts.

With this in mind, it’s important to weigh these pros and cons when considering enhanced gemstones. Although enhancements can make gemstones more visually appealing and affordable, it’s also possible to create durability issues, consequently affecting their value.

So it’s crucial to make informed decisions based on your preferences, budget, and the extra care you’re willing to provide for your gemstones.

What Does ‘Natural’ Mean for a Gemstone?

Having explored the world of gemstones, their color variations, and the pros and cons of enhancement techniques, it’s time to delve deeper into the concept of ‘natural’ gemstones. What makes a gemstone ‘natural’? And how does this naturalness impact its value and appeal?

As I mentioned earlier, a ‘natural’ gemstone has been formed over millions of years under natural geological processes. It is mined from the earth, cut, and polished, with no additional gem treatments or clarity enhancements to improve its apparent purity or color. The beauty of natural stones lies in their raw, untreated state, making each one a unique piece of nature’s art.

But the term ‘natural’ extends beyond the process of formation. It also encompasses the inherent characteristics of the gemstone, including its color, clarity, and inclusions.

These characteristics are a direct result of the gemstone’s chemical composition and the conditions under which it was formed. They contribute to the gemstone’s uniqueness and add to its aesthetic appeal.

From a value perspective, the vast majority of natural gemstones are generally more valuable than their enhanced or synthetic counterparts. This is because natural gemstones are rare and each one is unique.

Their value is determined by a combination of factors, including their color, clarity, cut, and carat weight, also known as the ‘Four Cs’ of gemstone grading.

However, the value of natural stones is not just monetary. For many, natural gemstones hold a deeper, more personal value. They are cherished for their natural beauty, their connection to the earth, and the unique story that each one holds.

Whether it’s the deep blue of a sapphire, the fiery red of a ruby, or the vibrant green of an emerald, each natural gemstone is a testament to the earth’s artistic prowess, making it a prized possession for any gemstone enthusiast.

Natural Gemstones for Spiritual Connection

Beyond their aesthetic appeal and monetary value, natural gemstones hold a special place in the realm of spirituality. Many cultures around the world believe in the spiritual connection that these gemstones offer, using them for healing, protection, and spiritual growth.

Each natural gemstone is believed to possess certain energies or vibrations that influence the wearer’s physical, emotional, and spiritual well-being.

For instance, amethyst, with its deep purple color, is often associated with spiritual awareness and inner peace. It’s frequently used for meditation and is believed to enhance intuition and spiritual growth.

Similarly, rose quartz, known as the ‘love stone’, is believed to open the heart to all types of love – self-love, family love, platonic love, and romantic love. It’s also prized for the popular belief in healing emotional wounds and fostering forgiveness and compassion.

Then there’s black onyx, a powerful protective stone believed to shield against negative energies. Often used for grounding and balancing, it’s considered an aide, contributing to peacefulness and harmony.

These are just a few examples of how natural, untreated gemstones are used for spiritual purposes. The type of gemstone, its color, and even its shape can influence its spiritual properties, making each one unique in its spiritual connection.

It’s also important to recognize the spiritual connection with natural gemstones is a profoundly personal one.

What works for one person may not work for another. Because of this, when considering a gemstone for spiritual purposes, it’s crucial to trust your intuition and choose the one that resonates with you the most, whether it’s an enhanced gem or a natural stone, when weighing the pros and cons of gemstone enhancements.

We gemstone lovers find this spiritual aspect of natural, untreated gemstones fascinating. It adds yet another layer of depth to their appeal, making them not just objects of beauty but also tools for personal growth, spiritual exploration, and philosophy.

Basic Principles of Gemstone Enhancements With Color Treatment

One of the jewelry industry’s most techniques for color enhancements, heat treatment, can significantly improve the gemstone’s color.

Heat treatment of sapphire, originally pale in color, can transform the stone into a deep blue one, or even a brownish zircon into a colorless one. But it can also affect its value, especially if the treatment is not disclosed.

The same goes for the color-enhancing irradiation process that can transform an otherwise colorless diamond into a fancy-colored one–or a white topaz into a blue one.

While this process often creates stunning colors, it’s important to note that some of these colors may fade over time or when exposed to additional heat over the gemstone’s extended lifetime.

And then there’s dyeing, used to enhance or change the color of porous gemstones like turquoise or jade.

Dyeing can create vibrant colors, these colors may fade over time or when exposed to certain chemicals like common household cleaners, acidic chemicals, or body lotions that may come into contact with the stone.

And finally, there’s diffusion, a treatment involving a combination of heating with a coloring agent to create a surface layer on the gemstone.

Although it can create beautifully intense colors, it’s important to know that this color only superficially affects the stone’s surface, and can change its optical properties if the gemstone is recut or even re-polished.

When considering the pros and cons of gemstone enhancements, the natural, untreated gemstones and the facilitated beauty of enhanced gems are appealing additions to your collection based on their respective prices.

They each contribute to jewelry you’ll enjoy as beautiful gemstone art accents for everyday wear. That being said, it’s always a good practice to learn about the nature of the gemstone and its origin since both aspects contribute to its value and its allure in personal jewelry and home decor alike.
