Dandelion Paperweight - Made from a Real Dandelion (Full Sphere)

Is this a sphere, just flattened at bottom? 1/2 circle? dome shape? need to know what it looks like from side view.

Is it flat on the bottom? How does it not roll off?

When you turn it, do the puffs look like they warp and bend? Like nebula paper weights?

Why is there a blue tint in the glass-like sphere? i bought a d! just like this from etsy and it’s clear. i do not care for the blue tint in this one
