You arrange the gems that serve as material components for the spell in a circle around the objects you want to store, tracing transmutative sigils above each of them. While casting the spell, you set a command word as trigger for the spell.

When you finish casting the spell, the objects are pulled into the largest of the gems, becoming stored in stasis. A gem can hold up to 500 pounds of nonliving material. While stored, the material doesn't weather, age, or rot, and the stored miniaturized objects are just faintly visible in the center of the amber.

You can use an action to speak the command word, chosen while casting the spell, to end the spell's effect and release the stored contents of the gem onto the ground. The contents are also released when the spell is dispelled or more than 500 pounds of material are stored in the gem.
