It isn’t a stone. If you take one thing away from this, let it be that. People walk into jewelry stores or museums and see these golden, glowing nuggets and assume they’re looking at a mineral like quartz or topaz. They aren't. Amber is actually fossilized tree resin. It’s sticky stuff that oozed out of a tree millions of years ago, hardened, and somehow survived the crushing weight of geological history to end up on a necklace or in a display case.
Actually, it's a bit like a biological accident that turned into art.
Think about a pine tree in your backyard. If you nick the bark, it bleeds this thick, gooey syrup. That’s resin. It’s the tree’s immune system, basically. It rushes to the wound to seal it off from fungi and boring insects. Now, imagine that happens 40 million or 50 million years ago. The tree dies, falls over, gets buried in sediment, and under the right pressure and temperature—without oxygen—that resin undergoes a chemical transformation called polymerization. It turns into amber.
Why Everyone Gets Confused About What Is Amber
There’s a huge misconception that amber is just dried sap. You’ve probably heard people use the terms interchangeably. They shouldn't. Sap is the watery stuff that carries nutrients through the tree (think maple syrup). Resin is the thick, sticky defense mechanism. You can’t make amber out of sap; it just doesn't have the right chemical building blocks to polymerize.
The stuff is surprisingly light. If you hold a piece of glass and a piece of amber of the same size, the amber feels like nothing. It’s also warm to the touch. Because it’s organic, it doesn't pull heat away from your skin the way a cold diamond or emerald does. That’s one of the easiest ways to tell if you’re holding the real thing or a plastic fake.
Honestly, the variety is wild. Most people picture that classic "amber" color—a honey-gold or burnt orange. But it can be bone-white, butter-yellow, or even a deep, moody green. There’s even a rare blue amber found in the Dominican Republic that looks totally normal until sunlight hits it, and then it glows with an eerie, fluorescent blue tint because of hydrocarbons in the resin.
The Jurassic Park Factor: Inclusions and Time Travel
We have to talk about the bugs. This is what usually gets people interested in the first place. Because resin is incredibly sticky, it acts like a death trap for anything small enough to get stuck. Gnats, ants, spiders, even the occasional lizard or feathers.
When an organism gets trapped in resin, it’s sealed off from the air. This stops decay in its tracks. You aren't looking at a fossilized imprint in rock; you are looking at the actual creature, preserved in three dimensions. In 2016, researchers even found a feathered dinosaur tail trapped in a piece of 99-million-year-old amber from Myanmar. It still had the feathers. It’s a level of detail that traditional fossils just can’t touch.
But no, you can’t actually clone a T-Rex from it. Sorry.
DNA has a half-life of about 521 years. Even in the best-preserved amber, the genetic code breaks down into useless fragments after a few thousand years, let alone millions. What you see is a "ghost" of the insect—the chitinous shell is there, but the insides are usually long gone.
Where Does This Stuff Actually Come From?
Most of the amber you see for sale comes from the Baltic region—places like Poland, Lithuania, and Russia. This is "Baltic Amber," or succinite. It’s about 35 to 50 million years old and comes from ancient coniferous forests that are now under the Baltic Sea. After a big storm, pieces of it literally wash up on the beach like sea glass. People go out with nets to scoop it up.

Then there’s Dominican amber. It’s younger, maybe 15 to 25 million years old, and it comes from an extinct leguminous tree called Hymenaea protera. This stuff is famous for being incredibly clear. If you want to see a prehistoric fly with every tiny hair on its legs perfectly visible, you look for Dominican pieces.
How to Spot a Fake Without Being a Scientist
The market is flooded with fakes. Plastic, resin, and "copal" (which is just young resin that hasn't fully fossilized) are everywhere. If you’re buying a piece, you don’t want to get scammed by a piece of melted-down billiard ball.
- The Saltwater Test. Real amber is incredibly buoyant. If you mix about seven teaspoons of salt into a cup of water, real amber will float. Plastic or glass will sink like a stone.
- The Static Charge. Rub a piece of amber vigorously against a wool cloth for 20 seconds. If it’s the real deal, it’ll become electrostatically charged and pick up tiny bits of paper or hair. Ancient Greeks actually called amber elektron, which is where we get our word for "electricity."
- The Hot Needle. This one is a bit destructive, so don't do it to a museum piece. If you touch a hot needle to a discreet spot on the amber, it should smell like pine or burning incense. If it smells like acrid, burnt plastic? It’s fake.
Why Amber Is More Than Just Jewelry
Scientists use amber to reconstruct ancient ecosystems. It's basically a data disk from the Eocene or Cretaceous periods. By looking at the bubbles of air trapped inside, researchers can actually sample what the atmosphere was like millions of years ago. They can see what plants were growing, what parasites were bothering insects, and even how the climate was shifting.
It’s also a weirdly durable substance. While it can be scratched easily (it’s only about a 2 to 2.5 on the Mohs scale), it doesn't decay. It survives being tumbled in the ocean and buried under mountains.

There's something deeply human about our obsession with it, too. We've been using it for 13,000 years. Archaeologists have found amber beads in Paleolithic sites. Roman women used to carry amber balls in their hands to keep them cool (or warm, depending on who you ask) and because they liked the scent it gave off when rubbed. It was the "Gold of the North."
Is It Worth the Investment?
If you’re looking at it from a collector’s standpoint, value is all about the "inclusions." A clear piece of Baltic amber might cost you $50. A piece with a perfectly preserved, rare scorpion or a flower? That could go for thousands.
But for most people, the appeal is just that weird, tangible connection to the deep past. You're holding something that was liquid while mammoths were still millions of years away from existing.
Actionable Steps for New Collectors
If you're looking to start a collection or just want to buy a decent piece of jewelry, follow these steps:
- Check the origin. Always ask if it's Baltic, Dominican, or Burmese. If the seller doesn't know, walk away.
- Look for imperfections. Real amber is rarely perfect. It should have tiny "sun spangles" (circular fractures) or bits of organic debris inside. If it looks too clean, it might be pressed amber—which is real amber scraps melted together under heat—or just plastic.
- Buy from reputable dealers. Look for members of the International Amber Association. They have strict standards for what can be labeled as "natural amber."
- Avoid the "Bargain" Bug. If someone is selling a piece with a giant, perfect dragonfly for $20, it’s 100% fake. Insects in real amber are usually small and look like they’ve been through a struggle.
Understand that amber is a soft material. You can't just throw it in a jewelry box with diamonds; the diamonds will chew it up. Store it in a soft pouch, keep it away from hairspray and perfume (the chemicals can dull the polish), and clean it with nothing but warm water and a soft cloth. It’s been around for 40 million years; it’d be a shame to ruin it with a bit of Windex.
