Bubblegum Agate is a variety of botryoidal chalcedony characterized by its distinct, often soft pink to bubblegum-colored spherical structures. It is highly sought after by lapidary enthusiasts for cutting into cabochons due to its attractive patterns and pastel coloration.

Is this bubblegum agate?

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 bubblegum agate with a known reference. Bubblegum Agate sits at Mohs 6.5-7 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Bubblegum Agate leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Bubblegum Agate typically shows a waxy luster.
4
Match the color range
Compare against the expected color range: pink, white, translucent-pink.
5
Look at form & habit
Crystal system: trigonal. Typical habit: botryoidal.
