Helzberg Diamonds Bait large high quality diamonds with a price tag and claim they were placed by mistake, Internet

Diamond earrings displayed as 3/8 Carat total at a price clearly displayed next to the earrings.  When interested in purchasing you will be told the earrings were put there by mistake, as it is near Valentines Day and there are workers who are not well trained and experienced. 

So the diamonds are actually 1/2 carat and far more expensive.  Upon further interest of purchase you might be told that once again an inexperienced employee has misplaced the diamonds displayed, next to a price, and they are of a high quality.  Not worthy of the price displayed.  In fact, they don't have diamonds at that Carat, quality, and price.

The sales associate may explain their sympathy as its nearing Valentines day and their swamped with customers and sales associates that might be putting diamonds in "the wrong spot" like high quality large diamonds in lower price tag areas.
