Where can I buy beautiful collars for myself?

Question

PLEASE READ BEFORE YOU SUGGEST
I do NOT want collars for cats or dog, I want them for myself.
I do NOT want big chunky things of brushed steel or leather with great big studs or steel rings.
I DO want ones that look like pieces of jewellery but are actual lockable collars. They need to be femenine and pretty or bejewled.
Please do NOT just look on google or a similar search and give me a random page, I have been through hundreds, so much so that I am dreaming about collars (not that I mind).
Please do NOT just say look on e bay.
I am looking for names of speceffic sites....
Thank you.
(ps, I am over the age of consent at 26)
