Pros
Great place to learn how to become a better jeweler and grow your skills, if you are in an environment that takes full advantage of what the company provides. The benefits are also extremely generous with PTO and depending on the work environment, your schedule can be very flexible. Also being a jeweler means you are in a separate department from the sales side of the company and they have no authority over you, and your job as a jeweler isn't impacted by the sales side, you could be working inside a Jared, but it doesn't matter if the salesperson couldn't make the sale, and the money charged between the Service Center and the store is all just a number for tracking margin, so it's really nice being a jeweler that doesn't need to worry about sales or have a salesperson lord over you. It's very different than a mom and pop jeweler job.
Cons
Depending on the shop/manager your growth can be stagnanted. The company pushes for number of units and that's created a mentality of a focus for lesser quality workmanship to pass through QC. The store side salespeople don't get trained well on their side and will lean on the service center side to do the technical things for them. The sales staff knowledge on jewelry can be next to nothing because it's not a requirement for them, so that adds a lot of friction between jeweler and sales staff.
