Items in trade:

All magical (blues)
ring with +7% attack speed
pants socketed with Flawless Emerald and Flawless Amethyst
bracers (nothing special)

We have successfully traded in the past and do so quite frequently. We have tried trading the items 1 at a time, with\without socketed gems, with\without trade window, and we have traded other items successfully since then without consequence. Once game termination is complete and we log back in, all items are reset to where they were before the trade.
