While, undeniably, there are tomboys in this world, it is a historically proven fact that women like to adorn themselves, so much so that they would use any jewelry at their disposal, be it made of bone, stones (not precious), metals (not precious), wood, glass or even the infamous plastics of today. It is also a historically proven fact that men also like that, although, certainly, not to the same extent; it's enough to look at the narcissistic self-portraits of Albrecht Durer or even the much less handsome Rembrandt to see that.
Anthropologists and aestheticians alike have explained this by humans' attraction to beauty and, particularly, beautiful objects. But then, if it was only that, people could as well keep their jewelry pieces in their cases, instead of wearing them as often as they can. And fashion, in general, wouldn't be these days a multi-billion industry, if people were not obsessively tempted by any item perceived as a prospective embellishment. Further, obviously, this is something like an infectious disease, given that even such a fashion-indifferent person like the character played by Anne Hathaway in 'The Devil Wears Prada' ends by becoming fashion-conscious and stylish, to such an extent that she almost alienates herself and even her loving boyfriend.
So why do women like to wear jewelry so much so that engagement rings have become almost characters in their own right in contemporary American movies, and Samantha Jones in 'Sex and the City', for instance, would wear a mother of pearl necklace even on an invisible part of her body? It may be argued that jewels are perceived as a completion of a feminine appearance, fashion jewellery wholesale as the last touch before going public. You'll rarely see any woman putting on her jewelry while in her negligee or sweat pants at home. But she would try her earrings or whatever new piece of jewelry while alone in front of the mirror, but only if fully dressed. Well, the mirror in this case is her invisible audience.
Imagine now a long flowery chiffon skirt with a blouse to match, without bangles, hoop earrings and a long string of beads and then with them. In the first case, you'd feel immediately that something is missing. In the same way, imagine a V-neck silk blouse and a business suit with some mother of pearl studs and a thin white gold chain with a little mother of pearl pendant and then without them. In the second case, you'd surely feel a void. So, in order to always have what it takes to complete your appearance, whether informal or formal, you should definitely have a store of wholesale jewelry at home.
If even someone as strict and sensible, perfectly aware that she was no beauty, as Jane Eyre, or a person as modest and diffident about her beauty as Tess of the D'Urbervilles, or, finally, someone as ghastly-looking as the old Miss Havisham would still wear jewelry, it's obvious that jewels are considered by women to be beautiful additions to their selves, so neither beautiful objects, likely to be simply collected, nor sure embellishment devices, given that they could be worn by the plainest or oldest women. As such, jewels simply add aesthetic value, without transforming one into someone different or better-looking.
