There really is no depot for it, it takes a lot of searching. BTW, do you mean a planter or do you mean a vase?
A couple places that come to mind:
- High end jewelers and jewelry makers, Hamilton Jewelers, Tiffany, Cartier, ect.
- Bergdorf Home
- Niemans and saks.
- 'lifestyle' type shops like Dunhill, davidoff, ect.
- Other high end retailers such as Louis Vuitton, ect.
