In the world of gemstones, tanzanite stands as a mesmerizing testament to the natural wonders of Earth. Discovered only half a century ago in the foothills of Mount Kilimanjaro in Tanzania, this alluring gemstone has captivated jewelry enthusiasts with its stunning blue-violet hues and remarkable rarity. However, as technology continues to push boundaries, the jewelry industry has witnessed a significant transformation with the advent of lab-created gemstones. In recent years, tanzanite, once believed to be exclusive to Mother Nature, has found itself reimagined in laboratories through advanced techniques. This article explores the rising trend of lab-created tanzanite, its growing popularity, and its impact on the gemstone market.
What is Lab-Created Tanzanite
Lab-created tanzanite refers to a synthetic version of the natural tanzanite gemstone that is produced in a laboratory environment. Unlike natural tanzanite, which forms deep within the Earth’s crust over millions of years, lab-created tanzanite is made through a process known as crystal growth or flux fusion.
During the crystal growth process, scientists create conditions similar to those found in nature that enable the growth of tanzanite crystals. Flux fusion involves melting raw materials and carefully cooling them to form tanzanite crystals.
The resulting lab-created tanzanite shares the same chemical composition and crystal structure as its natural counterpart. In many cases, it is challenging to distinguish between natural and lab-created tanzanite with the naked eye, as they often have similar physical and optical properties.
Lab-created tanzanite offers several advantages over its natural counterpart. It is generally more affordable, as it can be produced in controlled conditions without the need for mining. Additionally, lab-created tanzanite typically has fewer inclusions, giving it a higher clarity grade compared to natural tanzanite.
It’s important to note that lab-created tanzanite is not an imitation or fake version of the gemstone. Instead, it is a genuine tanzanite with all the same properties, except that it was created in a lab rather than forming naturally in the Earth’s crust.
Can Tanzanite Be Lab Created
Tanzanite can be lab-created or synthetic. Synthetic tanzanite is produced in a controlled environment, typically using a process called “hydrothermal synthesis.” In this method, chemical elements are dissolved in water, and then heat and pressure are applied to grow tanzanite crystals over a period of weeks.
Lab-created tanzanite has the same chemical composition, physical properties, and optical characteristics as natural tanzanite, making it challenging to distinguish between the two without specialized equipment. The primary difference is that natural tanzanite is formed over millions of years in the Earth’s crust, whereas lab-created tanzanite is produced in a much shorter time frame in a laboratory.
One advantage of lab-created tanzanite is that it tends to be more affordable than natural tanzanite, making it a popular choice for those looking to acquire this gemstone at a lower cost. Additionally, lab-created gems are generally more environmentally friendly, as they do not involve mining.
When buying tanzanite, it’s essential to inquire about the stone’s origin and whether it is natural or lab-created, as this will impact its value and price. Reputable jewelers should disclose this information to their customers.
The Advantages of Lab-Created Tanzanite
Lab-created tanzanite addresses the concerns surrounding ethical sourcing and environmental impact often associated with mining natural gemstones. The extraction of natural tanzanite can result in habitat disruption and may even involve human rights issues in some regions. Opting for lab-created tanzanite ensures a conflict-free and environmentally conscious choice.
Quality and Consistency
The controlled environment of laboratories allows for precise and consistent production of tanzanite. Unlike natural gemstones, lab-created tanzanite exhibits minimal inclusions, enhancing its clarity and brilliance. Moreover, consistent quality and color make it easier for jewelry designers to match stones for exquisite sets.
Substitutability
Traditionally, natural tanzanite has been considered a high-end luxury due to its rarity and exclusivity. Lab-created tanzanite offers a more affordable alternative without compromising on its visual appeal. This accessibility allows a broader range of consumers to enjoy the beauty of this remarkable gemstone.
Enhanced Durability
Lab-created tanzanite possesses the same physical properties as natural tanzanite, including its impressive hardness on the Mohs scale. As a result, it is highly durable and suitable for everyday wear, making it an excellent choice for engagement rings and other frequently worn jewelry.
What stones can be made in a lab?
A wide variety of gemstones can be made in a laboratory using various methods. Some of the popular gemstones that can be synthesized in a lab include:
1. Cubic Zirconia:
Often used as a diamond simulant due to its brilliance and clarity.
2. Moissanite:
Another diamond alternative, known for its fire and brilliance.
3. Synthetic Diamonds:
Real diamonds created using high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) processes.
4. Synthetic Ruby:
Lab-grown rubies possess the same chemical composition as natural rubies and exhibit similar properties.
5. Synthetic Sapphire:
Like rubies, lab-created sapphires have the same composition and properties as their natural counterparts.
6. Synthetic Emerald:
Artificial emeralds with similar characteristics to natural emeralds.
7. Synthetic Amethyst:
Lab-grown amethysts, popular purple gemstones, are widely available.
8. Synthetic Aquamarine:
Created in a lab to resemble the natural blue gemstone.
9. Synthetic Opal:
Lab-created opals with vivid play-of-color patterns.
10. Synthetic Spinel:
Lab-grown spinels can mimic the colors and brilliance of natural spinels.
These lab-grown gemstones offer an ethical and often more affordable alternative to their natural counterparts, while still retaining their beauty and charm.
Conclusion
In conclusion, the world of gemstone manufacturing has witnessed a remarkable breakthrough with the successful creation of lab-grown tanzanite. Through advanced scientific techniques, researchers have unlocked the secret to replicating this exquisite gemstone’s stunning beauty in controlled laboratory environments. The journey to master this process has not only demonstrated the potential for creating an ethically-sourced and sustainable supply of tanzanite but has also provided invaluable insights into the gem’s intricate crystal structure.
The production of lab-created tanzanite has proven to be a testament to human ingenuity, showcasing the limitless possibilities when cutting-edge technology converges with nature’s wonders. With identical physical and optical properties to its natural counterpart, lab-created tanzanite stands tall as a testament to the triumph of science over scarcity.
The advent of lab-grown tanzanite promises to revolutionize the gemstone industry, offering consumers an ethical and affordable alternative without compromising on its brilliance and allure. As we step into a new era of responsible gemstone sourcing, lab-created tanzanite emerges as a shining symbol of progress and sustainability in the realm of precious gemstones.
