Technically, I'm wearing small gold earrings, but that's about it. I'm not really fond of wearing any other kinds of jewelry apart from earrings, so I would say that I would choose the real one rather than the fake or costume ones.
I don't own a lot of jewelry do I prefer to keep the few I've got original. When I used to buy costume jewelry, I noticed they weren't durable and wear overtime.
I don't particularly care (not at all) about this. I think this kind of expense is pure waste of money. It's a pity that my girlfriend does not think the same way I do.
For me it's a mixture of both real and costume jewelry. Real jewelry may seem to be more classy but are some costume jewelry that are pleasantly attractive and this will allow me to have a larger array of jewelry at a lower cost.
I'm not really into real jewelries because they are so expensive. I would always go for costume jewelry. Some costume jewelries are nice and at an affordable and reasonable price.
I certainly like real jewelry and precious metals. But it's expensive, I can't afford to buy much. And jewelry is inexpensive, so I have a lot of jewelry.
