You seem to be confusing the history of chokers ( a new name for an old piece of jewelery ) with symbols of bondage.
During the Victorian era, nearly every woman of quality owned an expensive black velvet ribbon, from which to hang their costly heirloon cameo.
The S&M stuff got popular in the '70's, which is recent history. Don't let the fact that the freaks stole a tradition confuse you about the origins of that tradition.
One peice of jewelery you SHOULD take exception to is the nose ring. Throught history - until now, that is - the nose ring was a symbol of slavery. Freemen didn't wear them. Yes, in Briton 1,000 years ago, white male slaves wore the collar. Not females.
I hate them anyway, but they are also extremely unhealthy.
In fact I have a wonderful choker that I bought at Neiman Marcus years ago that always gets comments. A black cord tied around my neck with an astounding heavy Barry Kieselstein-Cord cross. Oh, and one from Barney's New York ... a 24K choker chain with a filigreed cross with an emerald in the middle. Hmm, think I'll wear that one to work tomorrow.
