These little items can be used to embellish something plain, bring some coordination to something that otherwise might look disjointed, or just stand out as statements on their own.
Earrings I think of earrings as being sisters, but not necessarily identical twins. Some designs lend themselves to symmetry, which is how most people wear their earrings. That is, the left and right are identical. I much prefer balance. Interest is created by tension. A pair of such earrings will have a unifying element (design, size, material), but each one will be unique.
Got a chain, but need a new look, just add one of these pendants!
Or, purchase a pendant with one of the ready made chains that I keep in stock.
Necklace I am sometimes asked if I have a "set", that is, matching necklace, earrings, bracelet, etc. While I can make such a beast, I prefer not to. Life is too full of the easy way out......a big box store concept......just get everything to match and you are good to go. This is a concept that dates itself. A more interesting look is one in which the separate elements coordinate with each other. Or, better yet, complete a look with a statement piece!
