Selling Thomas Knoell pieces

My wedding is at the end of the month, and once we return from the honeymoon I want to sell my Thomas Knoell headpiece & earrings.

I have the destiny headpiece, and matching chandlier earrings. The set cost me almost $800. I will only have worn them once.

Where would be the best place to sell these items? What is a fair amount to ask for them?

I don't want to sell them, but after the wedding fun is over it will be responsible thing to do!

I'll keep an eye out for pics. TY

Even though you're selling AFTER the wedding, you can post pics now. No harm in that. You might be able to sell it quicker that way.
