Does this urn have a threaded lid for securing the ashes within?
The lid is not threaded.
This cremation urn is a rich deep color and will hold the ashes of an adult. Rich deep color, green is the most predominant color on the planet and symbolic of nature. Shades of emerald baked into this fine art cloisonne which is a metal blend of copper, brass and enamel. Excellent quality and craftsmanship. This size works well for niche placement at the cemetery and many families that store the ashes in the home choose this style because it blends in to the decor.
