Amber, fossilized tree resin, captivates with its warm glow and ancient history. However, the market is flooded with imitations, making it crucial to know how to distinguish genuine amber from counterfeits. This guide provides comprehensive methods for authenticating amber, empowering you to make informed purchases and appreciate the true beauty of this natural treasure.
What is Amber and Why is Authenticity Important?
Amber is a gemstone formed from the fossilized resin of ancient coniferous trees. Its age can range from millions to hundreds of millions of years old, making each piece a unique window into the distant past. The value of genuine amber lies not only in its beauty but also its historical significance and rarity. Counterfeit amber, often made from plastic or glass, lacks this rich history and intrinsic value. Authenticating amber protects you from fraudulent purchases and ensures you're investing in a genuine piece of natural history.
How to Identify Real Amber: Key Tests and Techniques
Several methods can help determine the authenticity of amber. It’s best to employ a combination of these techniques for the most reliable results:
1. The Saltwater Test:
This is a widely known and readily accessible test.
-
Method: Fill a glass with saltwater (a solution of roughly 1:4 salt to water). Gently place the amber in the solution. Real amber, being less dense than saltwater, will float. Many imitations will sink.
-
Caveats: This test isn’t foolproof. Some plastics may also float, so it's crucial to use this test in conjunction with others.
2. The Heat Test (Use with Caution!):
This test requires careful handling to avoid damaging the amber or causing injury.
-
Method: Gently heat a needle or pin with a lighter and touch it to an inconspicuous area of the amber. Real amber will release a distinct piney scent, while plastic will melt or burn with a harsh chemical odor.
-
Caveats: This test carries a risk of damaging the amber. Use extreme caution, applying only minimal heat for a short period. It’s recommended to test a small, hidden area.
3. The UV Light Test:
Many, but not all, types of amber fluoresce under ultraviolet (UV) light.
-
Method: Shine a UV light (e.g., a blacklight) on the amber. Genuine amber may exhibit fluorescence, often showing a bluish or greenish glow. However, not all amber fluoresces, and some plastics can mimic this effect. Therefore, consider this a supplementary test.
-
Caveats: The fluorescence reaction varies depending on the type of amber and the wavelength of the UV light used. The absence of fluorescence doesn’t necessarily indicate a fake.
4. Examine the Inclusions:
Natural amber often contains inclusions—small organic materials like insects, plant fragments, or air bubbles—trapped within the resin during its formation.
-
Method: Carefully examine the amber with a magnifying glass or loupe. The presence of naturally occurring inclusions can be a strong indicator of authenticity. However, some forgeries may contain artificial inclusions.
-
Caveats: The absence of inclusions doesn't automatically mean the amber is fake, as some types of amber are naturally inclusion-free.
5. Check for Surface Texture and Irregularities:
Authentic amber typically shows natural irregularities in its surface texture.
-
Method: Examine the surface carefully for inconsistencies, such as slight pitting, small bumps, or variations in color and transparency. Perfectly smooth, uniform pieces are more likely to be imitations.
-
Caveats: While this provides a clue, it shouldn't be solely relied upon.
Where to Buy Authentic Amber: Tips for Safe Purchasing
To avoid purchasing counterfeit amber, it’s essential to buy from reputable sources.
- Reputable Jewelers: Established jewelers with a history of dealing in gemstones are more likely to sell authentic amber.
- Specialized Amber Dealers: Seek out businesses that specialize in amber and have expertise in its authentication.
- Online Marketplaces (with caution): While online marketplaces can be convenient, exercise extreme caution. Thoroughly research sellers, read reviews, and request detailed information and authentication documentation before purchasing.
Is it Amber or Copal?
Copal is a younger resin, often mistaken for amber. It's not as old, and therefore, not as highly valued. While similar in appearance, copal is softer and less resistant to scratches than amber. It often reacts differently to heat and solvent tests. A professional gemologist can typically distinguish between the two.
By combining these methods and purchasing from reputable sources, you can significantly increase your chances of acquiring authentic amber and appreciating this fascinating natural treasure. Remember, consulting a professional gemologist remains the most reliable way to definitively authenticate amber.
