how do jewellery shops make profits?

Answer 1

Just as someone stated above there is a "3 key" mark up on jewelry sold in the retail store such as a Kay or London Gold.
Whether they buy from a wholesaler or make the jewelry themselves they mark up the cost of that piece 3 times what it cost to make.
Not all store markup that high but the industry average for retailers is 3 times.

Answer 2

They make their profits the same way the grocery store, the gas station, the variety store, or any other products offered business makes its profits. They buy or make product at a cost and sell it for enough money to pay for their own overhead and other expenses, and put some in the bank so they can buy or make more products to sell.

Answer 3

retail stores of any kind buy their product from a whole seller. They get these items for often times less than 1/2 of what they charge the public. I'm not sure what the typical mark up on jewelry is though.

Answer 4

Buy product. Add a profit margin to the cost. Sell it.

Certainly you meant something else than what you've asked.

Answer 5

Like everybody else: buy low (wholesale) and sell high (retail)

Markup for jewelry is typically 300%, for a mall jewelry store.

They don't have a lot of turnover, but make big money on each one.
