FYI just so you know, there really is no longer a Google+ Local Page.
Think of your business info just being in Google's database. Then based on the situation Google will arrange and display that data in the 3 pack of search, or the knowledge panel, or the local finder or on your G maps listing. So those are the places your reviews and data from your dashboard can show up.
If you create a separate G+ page, it is just that - a separate social page - no reviews. That page won't rank, show up in search or maps and no one will see it unless you give them the link because you are actively posting and want them to be able to connect with you on social.
New advertising option:
A review of your product or service posted by a Sterling Sky employee. This will also be shared on the Sterling Sky & LSF Twitter accounts, our Facebook group, LinkedIn, and both newsletters.
