I'm not sure I know what you mean.  Are you referring to websites to post your work for sale? Buying jewelry/beads?

As for purchasing jewelry and/or beads, I am unaware of any that are considered "unsafe".  For selling your work, there are many from which to choose and, again, to my knowledge, am unaware of any that are "unsafe".

Do you want jewelry ideas? Or jewelry supplies? So far I have found www.firemountaingems.com to be the best jewelry supplier cuz they give a great all-assortable discount and they have amazing service, plus the site is very user friendly and they have a great Gallery-of-Designs that has great ideas. For jewelry ideas- no joke- I browse at Neiman Marcus, Coldwater Creek and any other stores that sell jewelry and accessories. They always have great ideas and it helps to keep up with the fashions!

Two great places to buy and sell jewelry are on etsy and artfire. I have bought and sold jewelry and supplies on both sites and have absolutely no complaints. My sites are http://bstrung.etsy.com and http://bstrung.artfire.com. There are thousands of other sellers on both sites. Give them a try I am sure the artists that make the jewelry and other goods will be happy to have you join.
