Ivory, prized for its beauty and rarity, has been a sought-after material for centuries. From intricate carvings to piano keys, ivory has found its place in various cultural artifacts and everyday items. However, the trade in ivory has had devastating effects on elephant populations and has led to strict regulations and bans in many countries. Identifying ivory, therefore, is crucial for ethical reasons as well as legal compliance.
Understanding Ivory: What is It?
Ivory is a hard, white material derived primarily from the tusks and teeth of elephants. This organic material is composed mainly of dentine, a substance also found in human teeth. The term “ivory” has also been used to describe similar materials from other animals, such as walruses, narwhals, and hippopotamuses, but elephant ivory is the most commonly known and used.
Historical Significance of Ivory
Throughout history, ivory has been revered for its aesthetic and practical qualities. In ancient times, ivory was used to create religious artifacts, jewelry, and decorative objects. Its smooth texture and ability to be finely carved made it a favorite among artisans. The demand for ivory, however, led to the exploitation of elephant populations, which has had significant ecological impacts.
Why Identifying Ivory is Important
Identifying ivory is important for several reasons. Firstly, it helps in the conservation of elephants by ensuring that illegal ivory does not enter the market. Secondly, it assists law enforcement in tracking and preventing wildlife trafficking. Lastly, for collectors and consumers, identifying ivory helps in making informed and ethical choices regarding purchases.
Physical Characteristics of Ivory
To identify ivory, one must be familiar with its physical characteristics. Genuine ivory has a smooth, lustrous surface with a fine texture. It often exhibits a unique pattern called “Schreger lines,” which are intersecting lines visible under magnification. These lines form a cross-hatch pattern, distinguishing ivory from other materials.
Schreger Lines: The Signature Pattern
Schreger lines are a hallmark of elephant ivory. These lines can be seen in cross-sections of the material and are used to differentiate elephant ivory from other types. The angle of intersection of these lines can also help determine whether the ivory is from an African or Asian elephant. African elephant ivory typically has a smaller angle of intersection compared to Asian elephant ivory.
Other Methods of Identifying Ivory
Apart from visual inspection, there are other methods to identify ivory. One such method is the “hot needle test,” where a heated needle is pressed against the material. Genuine ivory will not melt or burn, whereas synthetic materials will show signs of melting. However, this method is destructive and not recommended for valuable or historical pieces.
Ultraviolet Light Test
Another non-destructive method is the ultraviolet light test. When exposed to ultraviolet (UV) light, genuine ivory fluoresces a white or bluish color, while synthetic materials and bone often show a different fluorescence. This test is useful for quick and non-invasive identification.
Comparison with Bone and Synthetic Materials
Ivory is often confused with bone and synthetic materials. Bone, unlike ivory, has a porous structure with visible tiny holes or pits. Synthetic materials, on the other hand, may mimic the appearance of ivory but lack the Schreger lines and the natural warmth of ivory. Detailed examination and comparison are essential for accurate identification.
Legal and Ethical Considerations
Due to the decline in elephant populations, many countries have implemented strict laws regarding the trade and possession of ivory. In the United States, for example, the sale of ivory is heavily regulated, with specific exceptions for antique items. It is crucial for buyers and sellers to be aware of these laws to avoid legal repercussions and support wildlife conservation.
The Role of Conservation Efforts
Conservation efforts play a pivotal role in protecting elephant populations and reducing the demand for ivory. Organizations worldwide are working to raise awareness about the consequences of ivory trade and promote the use of alternative materials. Supporting these efforts and choosing ethically sourced or alternative materials can make a significant impact.

Alternative Materials to Ivory
In response to the ivory trade ban, many artisans and manufacturers have turned to alternative materials that mimic the appearance and properties of ivory. These materials include bone, antler, and high-quality plastics. While they may not possess the same historical value as genuine ivory, they offer a sustainable and ethical option.
Educational Resources and Training
For those involved in the appraisal, collection, or sale of items that may contain ivory, education and training are essential. Various courses and resources are available that teach how to identify ivory accurately. These programs often cover the legal aspects, physical characteristics, and ethical considerations related to ivory.
Technology and Ivory Identification
Advancements in technology have also contributed to the field of ivory identification. Techniques such as DNA analysis and radiocarbon dating can provide precise information about the origin and age of ivory. These methods, while often more expensive and time-consuming, offer a high degree of accuracy and can be invaluable in legal and conservation contexts.
Public Awareness and Advocacy
Raising public awareness about the impacts of the ivory trade and the importance of conservation is crucial. Advocacy groups and conservation organizations work tirelessly to educate the public and promote policies that protect wildlife. By supporting these efforts, individuals can contribute to the global fight against illegal ivory trade.
Conclusion: The Importance of Identifying Ivory
Identifying ivory is not only a matter of expertise but also of responsibility. With the knowledge of ivory’s physical characteristics, historical significance, and the legal and ethical implications of its trade, individuals can make informed decisions that support conservation efforts. Whether you are a collector, seller, or simply an enthusiast, understanding how to identify ivory helps protect endangered species and preserve the natural world for future generations.
In Conclusion
The ability to identify ivory accurately and responsibly is an essential skill in today’s world. By combining traditional methods with modern technology and staying informed about legal regulations, we can ensure that our actions contribute to the preservation of elephants and other species affected by the ivory trade. Through education, advocacy, and ethical choices, we can make a positive impact on wildlife conservation and help put an end to the exploitation of these magnificent creatures.
