The global amber market is flooded with synthetic copal, pressed amber, and plastic imitations sold as genuine. For the untrained eye, distinguishing real Baltic amber from a convincing fake is genuinely difficult. This guide covers the tests you can perform at home, the red flags to watch for when buying online, and what certification to demand before any purchase.

How to Test Amber at Home
Salt water test: Dissolve 1 cup of salt in 2 cups of water. Place the amber in the solution. Genuine amber floats. Plastic, glass, and most copal sinks. This is the most reliable home test.
Static test: Rub the amber vigorously against a cloth for 20–30 seconds. Hold it near small pieces of paper or hair. Genuine amber develops a strong static charge and will attract these materials. Plastic and glass show minimal static.
Heat test (use carefully): Touch a hot needle (heated to red with a lighter) to an inconspicuous spot on the amber. Genuine amber produces a faint pine-resin smell. Plastic produces a chemical or burning smell. Do not use this test on finished jewelry.
UV test: Under UV light (a blacklight), genuine amber fluoresces blue or blue-green. Copal often appears yellow-white. Plastic shows minimal fluorescence.
Red Flags When Buying Amber Online
- Price well below $30 for a ring or pendant — genuine amber in sterling silver cannot be produced at this price
- No certificate of authenticity offered
- Descriptions using "amber-colored," "amber-style," or "resin"
- Perfectly uniform color and total absence of inclusions (genuine amber is never perfectly uniform)
- No information about amber origin or sourcing
What Genuine Baltic Amber Looks Like
Authentic Baltic amber has natural imperfections: slight variations in color across the stone, occasional tiny bubbles or plant inclusions visible under a loupe, and natural flow lines from the original resin movement during fossilization. The surface of polished genuine amber has a warmth and depth that plastic cannot replicate — it seems to glow from within rather than reflecting light off its surface.
