Natural color & dyed agate

Natural stone and natural color are different details

Agate is a banded form of chalcedony. A piece may be made from real agate and also have dyed color. Dyed does not mean the piece is made of plastic or glass. Look for the treatment description on the particular SKU.

What our product labels tell you

Our natural-color agate products and dyed color collections are described separately. Blue, teal, purple, pink and other color names should be read together with the product’s treatment disclosure. Do not use a photo alone to decide whether an agate is dyed.

Why pieces look different

Banding, translucency, rough outer edges, crystalline areas and outlines vary. A polished face reveals the stone’s pattern, but no stock image can promise an identical pattern in every piece. Ask about acceptable variation when planning a retail assortment.

Caring for dyed pieces

Keep dyed stone away from solvents such as alcohol or acetone, harsh cleaners and prolonged direct sunlight. These can affect color. Clean gently and follow the product guidance; do not assume a slice is suitable for food contact, heat or outdoor use.

Slices for creative projects

Check thickness, size range, piece count and drilling details before planning assembly. Our currently listed small agate slices are non-drilled. Discuss the attachment method and any custom requirements with us before ordering for a wind-chime project.
