Amber Barite is a golden, honey-colored variety of barite, best known from the Elk Creek area of Meade County, South Dakota, where sharp amber-colored crystals occur in septarian concretions. It shares barite's diagnostic properties: notable heft for its size, perfect cleavage, and a hardness of about 3.
Is this amber barite?
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 barite with a known reference. Amber Barite sits at Mohs 3-3.5, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: white.
- 3Read the lusterHold the specimen under a strong light. Luster: vitreous.
- 4Match the color rangeCompare against the expected color range: amber, golden yellow, honey.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: nodules, drops, irregular masses.

Field-hunting tip
Where it forms: sedimentary strata. If you start seeing glauconite, quartz, pyrite in float, you are in the right ground. Typical habit: nodules, drops, irregular masses. Train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in South Dakota. Start trip planning there.
