Aberforth somehow managed not to laugh though it was a fairly close run thing. Instead he simply arched an eyebrow and pretended to think about it. "I believe that there are vests that have shielding charms infused into them but I'm afraid I don't have any of those. And I suspect any of the amulets could be converted into an brooch. Any half-decent jeweller could do that for you."
He stepped away from the bar and disappeared out the back to his small, rather cluttered office. It only took a small amount of rummaging to unearth the small chest that held his current selection of magical amulets and he plucked out the three that held shielding charms. One was an agate and wire pendant, the second was a black Pearl pendant and the third was a silver intricate pendant. All three had shielding charms of roughly equal strength and it would be interesting to see which, if any, Lockhart chose.
He walked out of the office and back into the bar, placing the three amulets on the bar in front of Lockhart. "Shielding charms on all three," he said shortly, knowing a more knowledgeable man would test the charms but expecting Lockhart to simply be interested in which would look best with his clothes.
