Everyone like a good surprise that appears to offer a great deal. Lowes uses the concept in their big-box home improvement store by featuring a special item at a special price each day. You needn’t get that detailed to copy this promotion.
Pick a piece of jewelry you have in your case that you wish to move out. Create a “Deal of the month” promotional area and include the piece and a sign stating the original price (Say $995) for the item. Every Monday, lower the price by $50 until it sells. Frequent customers interested in the piece will visit the store multiple times checking on the current price and fighting the temptation to buy it now or wait until next Monday when it will be cheaper…or sold.
