Lean Green Gems - The monetization

I think the cost of the jewelry would be somewhere between the cost of cheap jewelry you see in shops and high-end jewelry. I expect the price to be between $50 - $200 for a pair of earrings. I expect the cost of manufacturing to be in the $30 - $150 range, evenly split between labor and materials. With intelligent use of machinery, there could be limited need for human labor, mostly assembly.  I expect the average price of a piece to be $100. The profit per piece would be roughly $30. Keep in mind that the quality would be of the same as most jewelry stores but 50% cheaper (because of the use of glass and other materials instead of stone).  

Because of the extensive use of kiosks, there would be very limited need for store employees. In fact, this could be done exclusively online.
