Your Favorite Jeweler will move to a new and a bigger location to serve you better, under a new name.

As a Brit and mentor, but not a teacher, I would have phrased it as follows:

To serve you better, your favorite jeweler (AmE) [jeweller (BrE)] will be moving to new, larger premises, under a new name, "New Name" on Monday, xth of June.

Hope this helps
