What Is Baltic Amber? Origin, History and How to Tell It Is Real

Baltic amber looks like a stone and is sold like a gem, but it is neither. It is tree resin, and it is older than the Alps.

What Is Baltic Amber?

Amber is fossil resin. Around 40 to 45 million years ago, a vast conifer forest covered northern Europe. The trees dripped sticky resin down their bark, the way a pine does today when it is cut. Over millions of years that resin was buried, hardened and washed into what is now the Baltic Sea.

Scientists call Baltic amber succinite. More than 90% of the world’s amber comes from the Baltic coast, and the ancient forest is thought to have produced over 100,000 tonnes of it.

Why It Feels Different from a Stone

Pick up a piece of amber and two things surprise you. It is warm, not cold like glass or stone. And it is so light it barely seems to be there. It is soft too, about as hard as a fingernail, which is why it has been carved by hand for thousands of years.

No two pieces look alike. Amber runs from pale lemon and honey through cognac and deep brown, with rare shades of red, green and even blue.

Life Trapped Inside

Sometimes an insect landed on the sticky resin and never left. Millions of years later it is still there, perfect down to the hairs on its legs. Insects make up almost all of the creatures found in Baltic amber, and scientists have named hundreds of species of beetle alone from them. Each one is a small window into a forest that vanished long before people existed.

Larger animals are far rarer, but they do turn up. One piece of Baltic amber holds a small gecko, right down to the pads on its toes. Scientists described it as a new species in 2005.

The Gold of the North

People have collected amber from Baltic beaches since the Stone Age. Pieces of Baltic amber found in Spain are more than 5,000 years old, so it was already being carried across Europe then.

The Romans loved it. A trade route known as the Amber Road ran from the Baltic shore to the Mediterranean, and amber travelled south along it to Rome.

The ancient Greeks called amber elektron. They noticed that when you rub it, it pulls dust and feathers towards itself. That is static electricity, and our word “electricity” comes from the Greek name for amber.

Looking for Amber After the Storm

Amber is still gathered the old way, and anyone can try it. On the Baltic coast, in seaside towns such as Palanga in Lithuania, the best days come after a windy night. Amber is only slightly heavier than sea water, so big waves lift it off the seabed and leave it on the beach, tangled in dark seaweed.

In the morning the shore fills with people. Some wade into the surf with long-handled nets and scoop up the seaweed. Families walk the tideline with children, turning the weed over by hand. Most pieces are no bigger than a grain of rice, golden and warm in the sun. Now and then a child holds up one the size of a hazelnut, and that is the one the whole family talks about for years.

Lithuanians have a legend to explain it. The sea goddess Jūratė lived in an amber palace under the waves and fell in love with a fisherman called Kastytis. The thunder god was furious and smashed the palace with lightning. The amber that washes ashore after a storm is said to be the pieces of her palace, and the smallest ones are her tears.

Palanga is also home to one of the great amber collections. Its Amber Museum, in a nineteenth-century palace near the sea, holds about 28,000 pieces, around 15,000 of them with an insect, a spider or a plant inside. The star of the collection is the Sun Stone, a single piece of amber weighing more than 3.5 kilograms.

How to Tell Real Amber from Plastic

Four simple checks you can do at home:

  • Warmth. Real amber feels warm in the hand straight away. Glass feels cold.
  • Weight. Real amber is very light for its size.
  • Salt water. Stir plenty of salt into a glass of water. Real amber floats. Glass and most plastics sink.
  • Static. Rub it on wool or cotton for a few seconds. Real amber will pick up tiny scraps of paper.

Old Beliefs About Amber

For centuries people wore amber as a charm. It was thought to bring luck and to keep its owner safe. We cannot promise it will do either, but we understand why something that holds 40 million years of sunlight feels a little magical.
