Copal is a semi-fossilized tree resin that is significantly younger than amber, often displaying a sticky surface when touched with a solvent like acetone. Collectors look for unique insect or botanical inclusions, though the material is much softer and more soluble than true amber. It is typically found in recent geological deposits rather than ancient fossil beds.

Is this copal?

5-step field check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

  • 1
    Test the hardness
    Try to scratch copal with a known reference. Copal sits at Mohs 1.5-2.5 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Copal leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Copal typically shows a resinous luster.
  • 4
    Match the color range
    Compare against the expected color range: yellow, orange, brown, pale yellow.
  • 5
    Look at form & habit
    Typical habit: amorphous.

Field-hunting tip

Look in sedimentary deposits country — that is the host setting where copal typically forms. If you start seeing none in float, you are in the right ground. Field specimens usually show a amorphous habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify copal?+
Mohs hardness is 1.5-2.5. It typically shows a resinous luster. The streak is white. Common colors include yellow, orange, brown, pale yellow.
Where is copal found?+
Notable localities include Colombia; Madagascar; Dominican Republic; East Africa.
How much is copal worth?+
Typical asking prices fall in the range of $5-50 depending on inclusion size and clarity. Quality, size, and provenance can move individual specimens well outside that range.
What rocks look like copal?+
Copal is most often confused with Amber. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with copal?+
Copal commonly co-occurs with none. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does copal form in?+
Copal typically forms in sedimentary deposits. Working float back to the host body is the standard way to chase a fresh occurrence.
What is copal used for?+
Copal is used in collector, decorative, lapidary.
