Jewelry design is one of those over democratic things , which lets you show the world who you are, by placing objects that have a cultural significance on your neck, ears, arms and fingers. I jest when I say over-democratic as it is indeed a very valid form of personal expression, but I do believe people have to be more aware of the fact it does work as a visual enhancement of who you are or want to be.
The best example for this case would be a pearl necklace versus earings with a colorful feather hanging from them.
For the record, my wife has many feathers in her jewelry box, but she is a Thai born painter and ex-hippie with the most bizarre beautiful wardrobe , so it fits perfectly. If I were a politician or a banker (ahhhh…just had a cold shiver running up my spine) she would probably have had a nice perfect pearl necklace to go with a Chanel suit. These are of course extremities but it works throughout the whole spectrum of jewelry, and jewelry design for that matter.
