Authentic amber, fossilized tree resin, is a beautiful and valuable material. Unfortunately, its desirability makes it a prime target for counterfeiting. Learning how to identify real amber from imitations is crucial for both collectors and buyers. This guide will provide you with several methods to determine the authenticity of amber, helping you confidently navigate the world of this ancient treasure.
What is Amber and Why is it Important to Authenticate?
Amber is formed from the fossilized resin of ancient trees, primarily conifers. Millions of years of geological processes transform this sticky resin into a hard, translucent substance, often containing fossilized insects or plant matter – inclusions that greatly increase its value and intrigue. Because genuine amber is relatively rare and prized for its beauty and historical significance, the market is rife with imitations, ranging from cheap plastics to cleverly disguised substitutes. Identifying real amber is vital to ensure you're making a worthwhile investment or acquiring a genuine piece of natural history.
How to Tell if Amber is Real: Key Tests and Techniques
Several methods can help you distinguish genuine amber from its imitations. It's best to use a combination of these techniques for the most accurate assessment.
1. The Saltwater Test
This is a widely used and relatively simple test.
-
Procedure: Fill a glass with saltwater (approximately 1 part table salt to 2 parts water). Carefully place the amber piece into the solution. Real amber, being less dense than saltwater, will float. Many imitations, such as plastic or glass, will sink.
-
Important Note: This test isn't foolproof. Some treated amber or certain types of imitations might also float. Consider this a preliminary test, not a definitive one.
2. The Heat Test (Use with Extreme Caution!)
This test is less recommended due to the risk of damaging the amber, but it can provide further insight.
-
Procedure: Gently heat a metal needle and touch it to the amber's surface. Real amber will release a slightly piney or resinous odor. Imitations will often release a harsh, acrid smell, or no scent at all.
-
Caution: This test carries a high risk of damaging the amber. Only perform it on an inconspicuous area, and with extreme caution to avoid overheating and cracking the amber.
3. The UV Light Test
Certain types of amber fluoresce under ultraviolet (UV) light.
-
Procedure: Shine a UV light on the amber. Genuine amber can exhibit a variety of fluorescent reactions, from bluish-white to greenish hues. However, not all amber fluoresces, and some imitations might mimic this reaction. This test should be combined with others for better accuracy.
-
Important Note: The color and intensity of fluorescence can vary greatly depending on the type of amber and the UV light source.
4. Examining Inclusions
If the amber contains inclusions (fossilized insects or plant matter), carefully examine them.
- Procedure: Use a magnifying glass to study the inclusions. Inclusions in genuine amber often display three-dimensionality and appear trapped naturally within the resin, rather than painted or artificially added. Fake inclusions frequently lack depth or realism.
5. Checking for Surface Texture and Color
Authentic amber displays a range of natural variations in color and texture.
- Procedure: Observe the surface of the amber. Look for natural inconsistencies in color, transparency, and texture. Imitations often have a uniformity and smoothness that is unnatural. Genuine amber often displays subtle imperfections and variations in tone.
6. The Friction Test
Rubbing amber can produce static electricity.
- Procedure: Rub the amber vigorously with a soft cloth. If it attracts small pieces of dust or paper, it suggests it might be genuine, though this is not a conclusive test on its own. Many other materials also generate static.
Addressing Frequently Asked Questions
Can amber melt?
Yes, amber has a relatively low melting point compared to other gems. However, it doesn't melt easily at room temperature. The heat test mentioned above utilizes a localized application of high heat to detect the characteristic smell.
How can I distinguish between amber and copal?
Copal is a younger resin, often mistaken for amber. Copal is softer, less resistant to scratching, and often lacks the same depth of color. While copal can also float in saltwater, further tests are needed to differentiate it from true amber. Copal frequently has a tacky or sticky surface and a less significant scent when heated.
Is it possible to test amber's authenticity at home?
Yes, the saltwater test and the careful observation of surface texture and inclusions are relatively easy to perform at home. However, for higher-value pieces or when absolute certainty is required, professional gemological testing is recommended.
Where can I get my amber professionally tested?
Reputable gemological laboratories and universities with geology departments often offer amber authentication services. They utilize advanced techniques like refractive index measurement and spectroscopy to provide definitive identification.
By using a combination of the methods described above, you'll be well-equipped to assess the authenticity of amber. Remember, using multiple tests offers the most reliable results. If you're unsure, seeking professional appraisal is always the safest course of action, especially for valuable pieces.
