Amber

What is Amber? — The Only Organic Fossilised Gemstone

Amber is fossilised tree resin — the hardened, polymerised remains of the sticky, aromatic resin that ancient trees produced millions of years ago as a defence mechanism against insects, fungi, and physical damage. It is important to understand from the outset that Amber is resin, not tree sap. Sap is the fluid that circulates through a tree's vascular system — like blood in a body. Resin is a separate, aromatic, semi-solid substance secreted through the tree's outer cells specifically to protect against injury and disease. This resin, when produced in sufficient quantity and under the right conditions, oozed from ancient bark and branches, dripped to the forest floor, and began its extraordinary multi-million-year journey of transformation.

The process of amber formation is called polymerisation — a chemical transformation in which the organic compounds within the resin gradually bond together into increasingly stable, increasingly complex molecular structures. First the volatile terpene compounds evaporate, leaving a stickier, more stable proto-resin. Then, as the resin is buried under layers of sediment, heat and pressure over millions of years drive the polymerisation further, producing first copal (a partially hardened intermediate stage) and finally true amber — a fully stable, fully fossilised, chemically inert organic solid that will remain unchanged for millions of years more. This process takes a minimum of several million years; most commercially available Amber is between 30 and 100 million years old.

Amber in History — Gold of the North

Amber's relationship with humanity is one of the most ancient, most continuous, and most globally far-reaching gemstone stories in history. The oldest known Amber jewellery pieces date back over 10,000 years — to the Neolithic period, when Baltic peoples crafted Amber into pendants, beads, and protective amulets long before any written record of their culture survives.

Ancient Egyptians used Amber in jewellery, protective talismans, and medicinal preparations — traces of Baltic Amber have been found in Egyptian tombs dating back 3,000 years, evidence of the extraordinary reach of the ancient Amber trade. Ancient Greeks called it elektron and believed it had magical properties — the static electricity it produced through friction seeming to them evidence of its connection to supernatural forces. Romans were so obsessed with Amber that Pliny the Elder devoted an entire section of his Natural History to it, and during the reign of Emperor Nero, a small amber figurine commanded a price greater than a slave — extraordinary testimony to how highly the Romans valued this golden organic gem.

The great Amber Road trade network — carrying Baltic Amber from the North Sea coast southward through Europe to the Mediterranean — was one of the defining commercial and cultural forces of the ancient world, spreading not just Amber but ideas, customs, languages, and technologies across thousands of miles of prehistoric Europe. In India, Amber has been used in Ayurvedic medicine, in sacred rituals, and in jewellery traditions for thousands of years — its warm golden colour, its pleasant resinous fragrance when warmed, and its purported healing properties giving it a cherished place in Indian cultural and healing heritage.

Did You Know? — Extraordinary Facts About Amber

The word electricity comes from the Greek word for Amber: When ancient Greek philosopher Thales of Miletus (around 600 BCE) rubbed a piece of Amber on wool, he observed that the Amber attracted small objects — feathers, bits of straw, ash — as if by an invisible force. He had discovered what we now call static electricity. The Greeks called Amber 'elektron' — and it is directly from this Greek word for Amber that the English word 'electricity' and the entire language of modern electrical science derive. Every time we use the word electric, electronic, electron, or electricity, we are unknowingly referencing a piece of ancient fossilised tree resin. This etymological connection between Amber and the foundational concept of modern physics and technology is one of the most remarkable and most profound intersections of natural history and human knowledge.

Amber gave us our first window into prehistoric life and inspired one of cinema's greatest stories: Long before Jurassic Park made amber-preserved DNA a household concept, scientists had been extracting genuine scientific knowledge from Amber's inclusions for centuries. Over 1,000 extinct animal species have been identified exclusively through their preservation in Amber — organisms for which no other fossil record exists and which would be entirely unknown to science without the extraordinary preservation that Amber provides. Ancient mosquitoes, spiders whose webs are still intact, beetles, ants, flowers, feathers, and even hair have been found perfectly preserved in their tens-of-millions-year-old golden tombs. Michael Crichton's Jurassic Park brought this scientific reality to global popular consciousness — and since its release, amber pieces containing mosquito inclusions have become among the most sought-after and most valuable collector specimens in the world.

Amber can float on salt water and feels warm to the touch — unlike any other gemstone: Amber has a specific gravity of approximately 1.08 — close to that of salt water — which means that genuine Amber will float or nearly float in a saturated salt water solution, while most imitations (glass, plastic, synthetic resin) will sink. This is one of the simplest and most reliable non-destructive tests for genuine Amber. Equally distinctive is Amber's thermal character: because fossilised resin is a very poor conductor of heat, Amber always feels warm to the touch — unlike mineral gemstones, which feel cool or cold when first held. This warmth — immediate, gentle, and unlike any mineral — is one of Amber's most immediately distinctive and most consistently reported physical qualities, and one that its healers and wearers have noted and cherished for thousands of years.

The Amber Road was one of humanity's most ancient and most important trade routes: Long before the Silk Road connected China to Rome, another great trade route connected the Baltic Sea — source of the finest Amber — to the Mediterranean civilisations of ancient Egypt, Greece, and Rome. This route, known as the Amber Road, carried Baltic Amber southward along the Vistula and Dnieper rivers, overland through Europe, and ultimately to the markets of Italy, Greece, Egypt, and the Middle East. Amber was so prized by the Romans that during the reign of Emperor Nero, a small amber figurine could command a price greater than that of a healthy slave. This extraordinary demand drove a trade network of thousands of miles that preceded and predated even the Silk Road — making Amber one of the earliest drivers of long-distance international commerce in human history.

Amber is the only gemstone where inclusions dramatically increase rather than decrease value: In every other gemstone family — Diamonds, Sapphires, Rubies, Emeralds, and all others — inclusions are flaws that reduce clarity, diminish beauty, and lower price. Amber is the sole exception to this universal gemological rule. In Amber, inclusions — particularly well-preserved prehistoric insects, spiders, and other organisms — transform an ordinary piece of golden resin into an extraordinary natural artefact of scientific and historical significance whose value can be many multiples of an equivalent piece without inclusions. A perfectly preserved mosquito in clear amber, a complete spider with all eight legs intact, or an ancient flower species known from no other fossil source can elevate a piece of Amber from a beautiful gemstone to a priceless window into geological time.

Amber Properties

Colour Varieties of Amber

Amber occurs in a remarkable range of colours — each caused by different combinations of tree species, geological conditions, and the presence of inclusions or impurities during fossilisation:

Inclusions — The Most Extraordinary Quality Unique to Amber

No other gemstone in the world is valued for its inclusions. In every other gemstone, an inclusion is a flaw — a reduction in clarity, beauty, and price. In Amber, inclusions are its most prized, most scientifically significant, and most financially valuable quality. The reason is simple and profound: Amber's inclusions are not cracks or mineral crystals — they are living organisms from tens of millions of years ago, preserved in extraordinary three-dimensional detail by the same fossilisation process that created the Amber itself.

How Inclusions Form in Amber

When ancient trees produced their sticky resin, they created one of the most effective and most indiscriminate preservation traps in natural history. Insects that landed on or crawled across the flowing resin became stuck. As they struggled to free themselves, more resin flowed over them, enveloping them completely and cutting them off from oxygen and bacteria — the two agents of biological decay. Encased in an anaerobic, chemically stable environment, the trapped organism was preserved not through mineralisation (as in most fossils) but in its original organic form — its internal structures, its surface textures, even its colours sometimes intact after tens of millions of years.

What Has Been Found in Amber

• Insects — the most commonly found inclusions: Mosquitoes, ants, beetles, flies, gnats, moths, and hundreds of other insect species — many extinct and known from no other fossil source — have been found perfectly preserved in Amber. Well-preserved, clearly visible insect inclusions dramatically increase the value of any Amber piece.
• Spiders and arachnids — among the most sought-after by collectors: Complete spiders, sometimes with their webs still intact, have been found in Amber of extraordinary scientific and collector significance. Spider silk from tens of millions of years ago, preserved in three-dimensional detail, is one of Amber's most remarkable palaeontological treasures.
• Plant material — flowers, leaves, seeds, and pollen: Ancient flowers from species long extinct, seeds of plants no longer found anywhere on earth, and pollen grains preserved in molecular detail have all been recovered from Amber inclusions — providing palaeobotanists with direct evidence of ancient plant life unavailable from any other fossil source.
• Air bubbles — ancient atmosphere preserved: The air bubbles trapped within Amber contain actual samples of the atmosphere as it existed tens of millions of years ago — a direct chemical record of the earth's ancient air composition that scientists have used to study the evolution of our atmosphere.
• Feathers, hair, and vertebrate material: Feathers from ancient birds, strands of hair from mammals now extinct, and in exceptional cases small vertebrate body parts have been found in Amber, adding to its extraordinary palaeontological significance.

World Sources and Origins of Amber

Baltic Sea — The World's Premier Amber Source (70 to 90 percent of supply)

The Baltic Sea region — encompassing primarily Russia (Kaliningrad Oblast), Poland, Lithuania, Estonia, and Latvia — is the world's most important, most historically significant, and most commercially productive Amber source, responsible for 70 to 90 percent of all Amber in global supply. Baltic Amber formed 30 to 50 million years ago from the resin of ancient coniferous forests that covered what is now Scandinavia. It is distinguished by its high content of succinic acid — a naturally occurring organic compound present only in Baltic Amber and traditionally prized for its healing properties. Baltic Amber is found in marine sediments beneath and around the Baltic Sea, and has been washing ashore along the coasts of Poland, Lithuania, and Germany for thousands of years — earning its historical nickname Seastone and Gold of the North.

Dominican Republic — Clearest Amber and World's Only Blue Amber

Dominican Amber, formed 15 to 40 million years ago in the Caribbean forests of what is now the Dominican Republic and Haiti, is celebrated worldwide for two exceptional qualities: its extraordinary transparency and clarity — significantly clearer than most Baltic material — and its production of the world's only natural blue amber. Dominican amber also contains a remarkably high proportion of insect and plant inclusions, and its superior clarity makes these inclusions particularly visible and particularly beautiful. The blue amber variety — which transforms from dark golden-brown to vivid electric blue in natural sunlight — is found only in the Dominican Republic and represents one of the most extraordinary and most rare colour phenomena in the entire gemstone world.

Myanmar (Burma) — The Most Ancient Commercial Amber

Burmese Amber, known as Burmite, is by far the most ancient commercially exploited Amber in the world — uranium-lead dating has established its age at approximately 99 million years old, placing it in the Cretaceous period when dinosaurs still walked the earth. Burmite has been of immense scientific significance, with over 1,300 species described from its inclusions — more than from any other single Amber deposit. Its colour tends toward dark brown to near-black. Due to its extraordinary geological age, Burmite has become one of the most scientifically important natural materials in palaeontology, providing direct evidence of Cretaceous forest life from the time of the dinosaurs.

Mexico (Chiapas) — Cherry Red and Rich Colour Range

Mexican Amber, primarily from the Chiapas region of southern Mexico, is known for its exceptional colour range — from pale yellow through vivid orange to the celebrated deep cherry red, produced through natural oxidation processes over millions of years. Chiapas Amber is typically 22 to 26 million years old and is frequently very clear, displaying beautiful inclusions with excellent visibility. The deep cherry red variety is highly prized in jewellery for its rich, wine-like colour and warm, glowing beauty.

Canada, Sicily, and Other Sources

Amber has also been found in commercially meaningful quantities in Canada (particularly Alberta — associated with Cretaceous-era deposits), in Sicily (known as Simetite — producing beautiful red and fluorescent varieties), and in smaller quantities from numerous other locations worldwide including Sumatra and various parts of Europe.
