Remember the most important rule in laying out the jewelry: Everything that is far away will never be bought.
This rule seems obvious, but when it comes to the stores, many sellers, in my experience, violate it. They lay out and hang jewelry in the most inaccessible places: they hang jewelry on mannequins, lay necklaces and bracelets on high shelves.
Remember, if a client cannot see the jewelry closely and touch it, he will never buy it.
You can hang the jewelry on a mannequin, but then exactly the same piece should be in an accessible place so that the client can see it closely.
Of course, the simplest way would be to have a regular jewelry display somewhere on the table. But this is a very boring and ordinary option that buyers are used to. Such a display will not catch the eye and it won't give the jewelry some additional meaning and charm. Therefore, it is worth stopping at non-standard solutions.
