The style is called branching bubbles. The original design I can find is out of stock and $27,000 by Lindsey Adelman. But they are similar ones with a lower price point.

There is a vertical version of this I will attach in here. It may not be what you are looking for but it is an interesting concept. Try Lumens.com or Lampsplus.com you can usually find something close at a lower price point than $27,000. These are still going to be higher end price-wise (1-5K), but if your budget limits you a big box shop would give you the best price at the sacrifice of some quality. But, some people don't mind that. AllModern would have something I'm sure, and a Lowe's or Home Depot could probably order it for you.
