Can this urn go directly into a gravesite or does it need something to protect the urn?
Depends on your cemetery, you'll need to check. Some do require vault (outer container) others do not. We just had a burial this week with the cloisonne hummingbird urn and a concrete vault was required.
Will this urn support a 200 lb. women's ashes?
Can I get this in a larger size. I need one for a person that weighed about 300 lbs.

Purple Iris cremation urn symbolizes wisdom. Fine art metal cremation urn is excellent quality and craftsmanship. Beautiful in the home. Suitable for cemetery burial or columbarium placement. Matching cremation keepsakes and double capacity companion urn sizes available.
The Cloisonne process requires multiple firings that can result in imperfections in the finish. Residue from the kiln may be more visible in a cloisonne urn with a white background and may appear as small burn imperfections in the finish.
