Baltic amber is fossilised tree resin, formed 40–50 million years ago in the ancient forests around the Baltic Sea. It is the world's oldest and most abundant amber, prized for its warm golden colours and its unusually high succinic acid content (3–8%). Both an organic gemstone and a genuine fossil, no two pieces are ever the same.
We've handcrafted Baltic amber in Lithuania since 1999 — from raw stone still carrying the scent of ancient pine forests to finished jewellery. Here is everything worth knowing about this remarkable material.
Amber has been treasured for over 40,000 years — worn as amulets, traded across ancient Europe along the famous Amber Road, and buried with kings. Yet it is not a stone or a mineral at all. It is something far rarer: a living forest, frozen in time. Let's start at the very beginning.
A forest, frozen in time
Baltic amber began life as sticky resin oozing from ancient coniferous trees during the Eocene epoch, some 40 to 50 million years ago. When these trees were wounded — by storms, insects or growth — they released resin to seal and protect themselves, exactly as pine trees still do today.
Over millions of years, that resin was buried under forest floors, rivers and eventually the seabed. Heat, pressure and time drove out its volatile compounds and slowly transformed the soft, sticky resin into a hard, stable, fossilised gemstone. This process — called polymerisation — is what separates true amber from younger resins like copal, which never fully hardened.
Because it was once liquid, amber sometimes captured whatever touched it: air bubbles, plant fragments, and occasionally insects — perfectly preserved snapshots of a world that vanished long before humans existed.
Why Baltic amber is special
Amber is found in many places — the Dominican Republic, Myanmar, Mexico, Romania — but Baltic amber stands apart. It is the oldest and by far the most abundant amber on Earth, with roughly 90% of the world's known amber lying in the Baltic region. Geologists give it its own mineral name: succinite.
What truly sets it apart is chemistry. Baltic amber contains 3 to 8% succinic acid — more than any other amber in the world. This natural compound is the reason Baltic amber has been valued for its warmth, its faint pine scent and, across centuries of folklore, its supposed soothing properties.
It is also extraordinarily light — with a density barely above water — warm to the touch within seconds, and able to hold a static charge. The ancient Greeks called it elektron, the very root of the word "electricity," precisely because of this quality.
The many colours of amber
People imagine amber as a single honey-gold, but genuine Baltic amber spans a remarkable spectrum — determined by how the resin formed and how many microscopic air bubbles it holds. This variation is one of the surest signs you are holding the real thing.
| Colour | What causes it |
|---|---|
| White / royal | Countless tiny air bubbles scatter light |
| Butter / egg-yolk | Dense fine bubbles, cloudy and opaque |
| Honey / cognac | The classic clear, golden Baltic amber |
| Cherry / red | Natural oxidation and ageing over time |
| Green / blue | Rare — plant matter or light effects |
No two pieces of amber are alike — each one is 40 million years unrepeatable.
Where it comes from — and the Amber Road
Baltic amber is found around the shores of the Baltic Sea — with the richest deposits in the Kaliningrad region, Lithuania, Poland and Latvia. It is either gathered from beaches after storms churn it loose from the seabed, or mined from a geological layer known as "blue earth."
For thousands of years, this amber travelled south along the legendary Amber Road, a trade route carrying Baltic amber to Rome, Egypt and beyond. Amber beads have even been found in the tomb of Tutankhamun. In Lithuania, where we work, amber is woven into national identity — and the craft of shaping it is one of the oldest in Europe.
Gemstone or fossil?
The answer is both. Amber is classed as an organic gemstone — one created by living things rather than geological minerals, alongside pearl and coral. At the same time it is a genuine fossil: preserved organic material tens of millions of years old. When amber traps an insect, that insect becomes a fossil too — which is why amber has taught scientists so much about prehistoric life.
Wearing a piece of deep time
To hold Baltic amber is to hold something older than the Alps, older than the modern oceans, older than nearly everything on Earth's surface. Warm, light and glowing, it carries the memory of a forest that disappeared before humanity began.
At AMBER999, every piece is certified Baltic amber, handcrafted in Lithuania by the same workshops we've worked with since 1999. Each stone is unique, and each one carries its 40-million-year story with it.

Frequently asked questions
How old is Baltic amber?
Roughly 40 to 50 million years old, dating to the Eocene epoch. The resin was produced by ancient coniferous trees, then buried and fossilised over tens of millions of years.
What makes Baltic amber different from other amber?
Its age, its Baltic origin, and above all its high succinic acid content of 3–8% — more than any amber elsewhere. Baltic amber is the world's largest and oldest known deposit, and has its own mineral name: succinite.
Is Baltic amber a gemstone or a fossil?
Both. It's an organic gemstone used in fine jewellery, and simultaneously a genuine fossil — the preserved, hardened resin of trees that lived tens of millions of years ago.
Where does Baltic amber come from?
From around the Baltic Sea — the Kaliningrad region, Lithuania, Poland and Latvia. It's washed ashore by the sea or mined from a layer called "blue earth." Lithuania has one of the world's oldest amber-crafting traditions.
Why does Baltic amber vary so much in colour?
Colour depends on how the resin formed and how many microscopic air bubbles it holds — from cloudy white and butter-yellow to clear honey, cognac and deep cherry. This natural variation, and the fact that no two pieces match, is a hallmark of genuine amber.
