Hi Coastal,
If you will allow me, this is a cautionary tale. Make sure that if you're importing stone that it is palletized to American safety standards. Before I was FIRE, I worked in the flooring industry. One of my major accounts bought a shipment of wood flooring from China. When the shipment arrived, the company representative stopped by the store with his wife and kids. He decided to help unload the goods from the container. The load was stacked too high, without a spacer pallet for stability. The load shifted and collapsed, killing him. All for the want of a $5 spacer pallet. You can IM me for more info, but please, please, pay attention to the details. And make sure you are well insured.
As to what else to fill your container with, I'd suggest LED lightbulbs. I have them almost everywhere in my house. Two things I cannot buy here are small bulbs (about 3") that face upward, but cast light downward (Picture a light fixture over a dining room table, bulbs face up, light shines down.) Everything we've tried is too tall and sticks out above the glass lampshades. The other is chandelier lightbulbs with small bases. Can't find attractive ones anywhere.
Whatever you decide, good luck to you!
