Amber is fossilized tree resin that often preserves ancient insects, plant matter, and bubbles. It is lightweight, warm to the touch, and can be distinguished from modern resins like copal by its hardness and solubility in solvents. It is primarily recovered from coastal deposits and sedimentary shales.
Is this amber?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch amber with a known reference. Amber sits at Mohs 2-2.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Amber leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Amber typically shows a resinous luster.
- 4Match the color rangeCompare against the expected color range: yellow, orange, brown, red, white.
- 5Look at form & habitTypical habit: irregular masses, nodules, drops.

Field-hunting tip
Look in sedimentary deposits country — that is the host setting where amber typically forms. If you start seeing coal, lignite, clay in float, you are in the right ground. Field specimens usually show a irregular masses, nodules, drops habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in New Jersey, Maryland, New Mexico — start trip planning there.
