How to Tell Real Amber from Fake: Simple Tests to Identify Genuine Amber
Amber has fascinated people for thousands of years with its warm glow, organic origins, and frequent presence of prehistoric inclusions such as insects or plant matter. However, the market is saturated with imitations, including plastic, copal (young tree resin), and synthetic resins. To distinguish real amber from its many fakes, a combination of simple tests and observations can be used. Each of these methods relies on physical or chemical properties unique to genuine amber.

One of the easiest ways to begin assessing whether amber is real is the visual inspection. Real amber often contains small imperfections, such as trapped air bubbles, plant fragments, or ancient insects. These inclusions should appear naturally embedded and not glued or artificially placed. If the material looks too perfect, it might be fake or made of plastic. Real amber also often displays a soft, warm sheen rather than a glassy, overly reflective surface.
Another useful test is the saltwater flotation test. Dissolve about 7 teaspoons of salt in a glass of water and stir thoroughly. Real amber tends to float in saltwater due to its low density, while most plastic and glass imitations will sink. This test is nondestructive and simple to perform at home, making it one of the most popular ways to verify amber's authenticity.
The friction or warmth test involves rubbing the amber against a piece of cloth for about 30 seconds. Real amber becomes electrostatically charged through friction and can attract small bits of paper or dust. This phenomenon was even observed in ancient times and is where the word "electricity" originates-from "elektron," the Greek word for amber.
Heat testing should be approached with caution, especially on valuable pieces. If you gently heat the tip of a needle and press it into an inconspicuous spot, real amber will emit a pine-like, resinous smell. In contrast, plastic emits a sharp chemical or burnt smell. This test can damage the specimen, so it should only be used when absolutely necessary.
Ultraviolet (UV) light can also be used to differentiate real amber. Under UV light, genuine amber fluoresces in a bluish or greenish hue, while plastics and other resins often show no reaction or fluoresce differently. This test is popular among gemologists and collectors because it is both non-invasive and reliable.
Scientific methods include infrared spectroscopy and specific gravity tests, but these require professional equipment. For museum-grade or high-value specimens, such tests can definitively determine authenticity.
It's also helpful to understand the origin of the amber. Baltic amber, the most renowned variety, is found around the Baltic Sea and is roughly 44 million years old. Its age and location often influence its value. Copal, which is often sold as amber, is also tree resin but is only a few hundred to a few thousand years old and lacks the same polymerization and fossilization as true amber. While similar in appearance, copal is softer and more susceptible to solvents and scratches.
Interestingly, scientists have used amber to study ancient ecosystems. The insects and plants trapped in amber have been preserved in astonishing detail, offering a glimpse into prehistoric life. This fossilization of organic matter in resin has even inspired science fiction ideas such as extracting dinosaur DNA from amber-preserved mosquitoes.
By combining multiple tests and using critical observation, anyone can increase their chances of correctly identifying real amber. While some fakes are convincing, genuine amber always leaves subtle clues that, when pieced together, reveal its true nature.
