Alexandrite Comparison – Natural vs. Lab Grown

 

Alexandrite, a gemstone celebrated for its unique color-changing properties, has long captivated gem enthusiasts and collectors. As with many precious stones, advancements in technology have allowed for the creation of lab-grown versions of this fascinating gem. This article delves into the differences and similarities between natural and lab-grown alexandrite, helping you make an informed choice.

Origins and Formation

Natural Alexandrite: Discovered in the Ural Mountains of Russia in the 1830s, natural alexandrite is a rare variety of the mineral chrysoberyl. Its unique ability to change color—from green in daylight to red under incandescent light—is due to trace amounts of chromium in its structure. Natural alexandrite forms under specific geological conditions, making it extremely rare and often expensive.

Lab Grown Alexandrite: Lab-grown alexandrite, on the other hand, is created in a controlled environment using advanced technological processes. These stones are chemically, physically, and optically identical to their natural counterparts. The primary difference lies in their origin. Lab-grown alexandrite offers a more affordable and environmentally friendly option without sacrificing the gemstone's desirable properties.

Visual and Physical Properties

Color Change: Both natural and lab-grown alexandrite exhibit the stunning color change that the gemstone is famous for. The transition from green to red is a key characteristic that makes alexandrite so unique. While natural stones may vary slightly in their color intensity and shift, lab-grown alexandrite loose stones are crafted to maximize this captivating effect.

Clarity and Inclusions: Natural alexandrite often contains inclusions due to its formation process deep within the Earth. These inclusions can add character to the stone but may also affect its clarity. Lab-grown alexandrite tends to have fewer inclusions, resulting in higher clarity. For those seeking a pristine gemstone, lab-grown options can provide exceptional quality.

Durability: Alexandrite, whether natural or lab-grown, ranks 8.5 on the Mohs scale of hardness. This makes it a durable choice for various types of jewelry, including rings, necklaces, and earrings. Both types of alexandrite are suitable for everyday wear, with proper care ensuring they remain beautiful for years to come.

Ethical and Environmental Considerations

Sourcing: Natural alexandrite mining can have significant environmental impacts, including habitat destruction and resource depletion. Moreover, ethical concerns regarding mining practices in some regions can be troubling for conscientious consumers. Lab-grown alexandrite offers a solution to these issues. Produced in a controlled laboratory setting, these stones eliminate the need for mining and reduce environmental harm.

Cost: The rarity of natural alexandrite contributes to its high price. Lab-grown alexandrite provides a more budget-friendly alternative without compromising on the gem's visual and physical properties. This makes lab-grown alexandrite an attractive option for those looking to own a beautiful gemstone without the hefty price tag.

Conclusion

When it comes to choosing between natural and lab-grown alexandrite, personal preference plays a significant role. Natural alexandrite holds a certain allure due to its rarity and unique formation history. However, lab-grown alexandrite offers an equally stunning and more accessible alternative, appealing to those who prioritize environmental sustainability and ethical sourcing.

Whether you opt for a natural gem or a lab-grown alexandrite loose stone, you are sure to enjoy the mesmerizing beauty and remarkable color-changing properties that make alexandrite truly special.
