Guardian Black Onyx Stone Urn

Glossy black with subtle gray veining, the Guardian Black Onyx Stone Urn has a classic casket-inspired shape with a stepped lid and base, polished to a deep shine.

Stone brings natural weight and permanence to a memorial. Each piece has its own variations in color and veining, so no two urns are exactly alike.

Engraving can be added (up to 120 characters) for a name, dates or a short message.

Frequently Asked Questions

What size urn do I need?

A common guideline is one cubic inch of capacity for every pound of body weight before cremation, so a 225 cubic inch urn like the Guardian Black Onyx Stone Urn generally fits an adult who weighed up to about 225 pounds.

Can a stone urn be buried?

Yes. Stone urns are well suited to burial and are also popular for columbarium niches and home display. Many cemeteries still ask for an outer urn vault for in-ground burial, so check their rules first.

How do I care for a stone urn?

Dust with a soft, dry cloth. Avoid acidic or abrasive cleaners, which can etch or dull the stone, and keep it away from damp areas.

How quickly will my urn ship?
