Pick a business model for your jewelry dealer business. You can distribute jewelry wholesale to retailers, sell jewelry via a physical or online storefront, or sell jewelry via home parties. Choose more than one business model to maximize your profits. Obtain the permits needed to start a retail business in your area. Choose Your Type of Jewelry. Choose the type of jewelry you’d like to distribute, such as costume jewelry, fashion jewelry, or fine jewelry. You also should decide whether you want to focus on silver jewelry, gold and platinum jewelry, cubic zirconia jewelry, bead jewelry or others. Dealers make their money on the “premium,” the amount charged over the spot price. For a US Mint Gold Eagle, you may pay a premium of $60 above the spot price of gold. But before you assume that a gold dealer makes $60 per coin, you must also consider that dealers do not buy these coins at the spot price either.
