Soapstone is a metamorphic rock composed primarily of talc, giving it a distinctive greasy or soapy feel. It is prized by carvers for its extreme softness, which allows it to be shaped easily with simple hand tools before being hardened through heating or polishing.

Grey, green or brown, opaque, with a dull to slightly pearly surface
Soapstone is a talc-rich metamorphic rock and it is the softest thing you will ever collect: a fingernail marks it. It occurs in the same ultramafic and serpentine terrain as nephrite and chrysoprase, and it has been quarried for carving and for cookware for thousands of years because it is easy to work and holds heat. Appalachian and Vermont occurrences are the classic American ones.
Before you collect
Talc-bearing rock in ultramafic terrain can contain asbestos minerals. Carve and sand wet, wear a respirator, and never work it dry.
Straight answers
- Is it worth cutting?
- Carves with hand tools, which makes it the best introduction to stone carving there is. It will not take a high polish, and finished pieces mark easily, which is part of its character rather than a flaw.
- What is it really worth?
- Very low. Its worth is as a carving medium.
- Can you legally keep it?
- Ordinary personal-use collecting rules apply. Historic quarries are usually private.

Field-hunting tip
Look in metamorphic terrains country, the host setting where soapstone typically forms. If you start seeing talc, chlorite, magnesite in float, you are in the right ground. Field specimens usually show a massive habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Maryland, Connecticut, Pennsylvania. Start trip planning there.
