What is amber and how is it formed?

Close your eyes and imagine a dense, humid forest from over 40 million years ago. The air is steamy, saturated with the scent of needles and resin, and golden rays of sunlight pierce through the crowns of mighty trees. It is in such conditions that natural amber is born – a stone that defies classical mineralogical definitions. It is not a mineral in the strict sense but fossilized resin from prehistoric trees that has withstood the test of time to delight our eyes today with its warm glow.

Understanding how amber forms requires us to see nature as an infinitely patient artist. The Gold of the Baltic, as our native succinite is often called, is nothing more than the tears of long-extinct coniferous trees that, in response to bark injuries, sudden climate changes, or pest attacks, secreted a thick, sticky substance. This resin, flowing down the trunks, trapped insects, plant fragments, and even bubbles of prehistoric air, creating unique inclusions that today serve as fascinating windows into the past.

A journey through time: Eocene forests

To fully explore the mystery of this process, we must go back to the Eocene epoch. The areas of today’s Baltic Sea and Scandinavia were then covered by a vast continent called Fennoscandia. It was home to mighty pine forests dominated by amber pines (Pinus succinifera), although modern paleobotanical research suggests that the resin may also have come from trees of the Sciadopityaceae or cypress families.

The climate was much warmer then than it is today – almost subtropical. Violent storms, hurricanes, and seismic activity caused massive damage to trees. In response to these wounds, trees produced huge amounts of resin, which was meant to protect the injured tissues from infections and pests. Drops, stalactites, and resin deposits fell onto the forest floor, mixing with the soil. When we analyze how amber forms, the properties of this prehistoric environment prove crucial – without the right humidity, temperature, and subsequent geological processes, the resin would simply decompose.

The fossilization process of resin

The resin flowing from the tree is just the beginning of an incredibly long journey. Millions of years ago, due to tectonic movements and climate changes, amber forest areas were flooded by seawater. Resin deposits were covered by layers of sediments – sands, clays, and silts. The lack of oxygen (anaerobic environment) prevented decay and oxidation processes.

Deep underground, under high pressure and appropriate temperature, the process of polymerization began, meaning small hydrocarbon molecules joined into long, complex chains. Over millions of years, the soft, sticky resin gradually hardened, losing its volatile components (such as terpenes) and transforming first into copal, and eventually into true amber.

As natural stone experts, at Brazi we deal with this wonder of nature every day. From our many years of experience at Brazi Druse Jewelry, we know that it is precisely these millions of years of maturation in marine sediments that give amber its remarkable durability and unique character. Every piece that comes to our workshop carries the story of a long-lost world, recorded in its structure.

Physical and chemical properties

Once we understand how amber is formed, it’s worth looking at its extraordinary physical and chemical properties. Baltic amber (succinite) stands out among other fossil resins due to its high content of succinic acid (from 3% to 8%). From a scientific perspective, its approximate molecular formula is C₁₀H₁₆O. For detailed information, visit mineralogical sources about amber, which describe its complex chemical structure and the variety of types found worldwide.

Physically, amber is a relatively soft stone. On the Mohs scale, its hardness ranges from 2 to 2.5, which means it is prone to scratches but at the same time extremely easy to work with in jewelry making. Its density is close to that of seawater (about 1.05 - 1.10 g/cm³). This is why amber sinks in fresh water but floats freely on the surface of salt water – this property has helped gatherers distinguish genuine amber from fakes for centuries.

Another fascinating feature is its electrostatic property. When rubbed with wool or natural silk, amber charges negatively and attracts tiny dust particles or paper scraps. The ancient Greeks already knew this property, calling amber electron, from which the modern word "electricity" derives.

Magic and beliefs – the esotericism of amber

In lithotherapy, amber is considered condensed solar energy. For millennia, it has been attributed protective, cleansing, and healing properties. It is believed that wearing amber close to the body, especially near the solar plexus or throat, helps harmonize energy flow, relieve stress, and restore inner balance.

Ancient Romans wore amber amulets as protection against evil forces and diseases. In folk tradition, it was believed that amber tincture strengthens immunity, and the smoke from burning amber (which emits a pleasant, resinous scent) cleanses the space of negative vibrations. From an esoteric perspective, the warm, golden hue of this stone stimulates creativity, awakens optimism, and helps overcome life’s obstacles.

In our philosophy, every imperfection of the stone, every cloud or small inclusion, is not a flaw but a unique fingerprint of Mother Nature and undeniable proof of its authenticity. These details make the stone your personal talisman.

How is amber made in Brazi jewelry?

Knowing how amber is made, jewelry with it becomes not just an ornament but a true artifact worn on the body. The transformation of a raw lump into a stunning necklace, ring, or bracelet is a process requiring great precision, respect for the material, and craftsmanship. Raw amber retrieved from the sea is covered with a matte, oxidized crust. Only after its removal does the true beauty of the stone reveal itself.

The processing begins with selection and cutting. Then the stone is ground on special wheels, often using water to prevent overheating – amber is sensitive to high temperatures and could crack. The next step is polishing, which gives it a final, mirror-like shine. The cabochon cut (smooth, convex) is often used, which best showcases the stone’s inner life, its depth, and any inclusions.

We invite you to visit our signature Brazi Druse Jewelry workshop in Warsaw, at ul. Grzybowska 61/5 in the Platinum Towers building (00-845 Warsaw). Here we combine this extraordinary, prehistoric gift of nature with the highest quality silver and gold, creating modern forms that pay tribute to tradition while perfectly fitting contemporary fashion trends. When designing our collections, we always strive for the setting not to dominate the stone but to subtly highlight its natural warmth.

Amber jewelry care

Due to its organic origin and relatively low hardness, amber requires special care. To keep its extraordinary shine for years, follow a few simple rules. Above all, avoid contact with strong chemicals, detergents, and even perfumes or hair sprays. Chemicals can dull the stone’s surface and deprive it of its natural luster.

Amber jewelry is best cleaned with a soft, damp microfiber cloth. For stronger dirt, you can use lukewarm water with a bit of mild soap, remembering to dry the stone thoroughly after washing. Do not use ultrasonic or steam cleaners—they can irreversibly damage the resin’s structure.

It is also important to remember proper storage. Since amber scratches easily, store it in separate soft fabric pouches, away from hard gemstones (like diamonds, sapphires, or quartz) and metal parts of other jewelry. Also avoid prolonged exposure of amber to direct, harsh sunlight and heat sources (e.g., radiators), which can cause drying and cracking.
