Amber-colored quartz, typically known as citrine, is highly prized for its warm, golden hue. While much of the material on the market is heat-treated amethyst, natural amber-tinted quartz can be distinguished by its distinct trigonal crystal habit and lack of cleavage.
Is this amber quartz?
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 quartz with a known reference. Amber Quartz sits at Mohs 7, 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: yellow, orange, brownish-yellow, golden.
- 5Look at form & habitCrystal system: trigonal. Typical habit: prismatic crystals.

Field-hunting tip
Where it forms: hydrothermal veins, pegmatites. If you start seeing amethyst, smoky quartz, microcline in float, you are in the right ground. Typical habit: prismatic crystals. Train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in North Carolina. Start trip planning there.
