Hallmarks on Antique Gold Jewelry

Two hallmarks I'm having trouble id'ing. One is on a cameo necklace that has a mark that looks like stacked boxes in 3-D; the other is a rose gold ring with a W and what looks like wheat below it. I'm sure they are both solid gold as there is no brassing to be found anywhere but no idea what the gold content is (possibly 9ct?) Any help would be MUCH appreciated!
