You arrange the amber gems in a circle around up to five hundred pounds of non-living material, tracing transmutative sigils above each of them. The objects are then pulled into the largest gem, becoming stored in stasis. While stored, the material doesn't weather, age, or rot. The outline of the items are barely visible, suspended and miniaturized in the middle of the amber.

You can use an action to speak a command word, chosen while casting the spell, to release the stored contents of the gem onto the ground. The contents are also released if the spell is dispelled.
