Your first choice should be the funeral home handling the arrangements. Most funeral homes have a wide selection of urns in a variety of materials and styles. Many people purchase an urn of their choice in the preneed planning phase.
That eases the burden on loved ones since it is such a highly personal selection among colors, shapes, materials and artistic styles. Also, the choice depends to some extent on the planned final placement of cremated remains.
Today, urns range from environmentally friendly containers that dissolve in lakes, rivers and the sea to urns of permanent materials designed to remain intact for hundreds or even thousands of years. It really is a highly personal choice.
