How do I play muiltiple animations?

I have an diamond model in my game and I have two animations, one animation that makes it look like it floats and one rotate animation that rotates 360 degrees they are played in loop but I can’t make them both play at the same time

Put your diamond model underneath an empty GameObject. Place Animation components on both the empty parent and diamond objects with one animation on each, i.e. the diamond would float and the parent would rotate.
