A good expensive jewelry design for factory

[zenith quarry]

I just been building the factory put I can’t find a good one to do

I'm making my own up. The parts are really expensive so I'm starting with 4 inputs, 1 metal band and 3 jewelry. You have to get a cutter and a polisher before combining with the bands

@zenith quarry I uploaded a blueprint for a Jewellery warehouse on the workshop yesterday. It's the most optimized that I could think of. I'm eager to hear of any suggestions.

What's the cost of this?

Just under 15 million
