Citrine geodes consist of yellow-to-orange quartz crystals lining the interior of a rock cavity. Most commercially available citrine geodes are heat-treated amethyst, though natural citrine can also occur in this form.

Is this citrine geode?

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 citrine geode with a known reference. Citrine Geode sits at Mohs 7, softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Citrine Geode leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Citrine Geode typically shows a vitreous luster.
4
Match the color range
Compare against the expected color range: yellow, orange, brownish-yellow.
5
Look at form & habit
Crystal system: trigonal. Typical habit: prismatic crystals inside a hollow cavity.

How to tell apart: Topaz is the harder of the two (Mohs 8 vs. 7).

Often found alongside citrine geode

Minerals reported to co-occur with citrine geode. Spotting these in float or country rock is a strong cue you are in the right ground.

Field-hunting tip

Look in sedimentary basalt or volcanic rhyolite cavities country, the host setting where citrine geode typically forms. If you start seeing amethyst, calcite, goethite in float, you are in the right ground. Field specimens usually show a prismatic crystals inside a hollow cavity habit, so train your eye for that shape before scanning the outcrop.

What rocks look like citrine geode?+

Citrine Geode is most often confused with Topaz, Yellow Beryl. A quick hardness test and a streak check separate the look-alikes faster than color alone.

What minerals are found with citrine geode?+

Citrine Geode commonly co-occurs with Amethyst, Calcite, Goethite, Quartz. Spotting any of these in float or country rock is a useful trip signal.

What kind of rock does citrine geode form in?+

Citrine Geode typically forms in sedimentary basalt or volcanic rhyolite cavities. Working float back to the host body is the standard way to chase a fresh occurrence.
