Vintage tie tack trio, include one signed sterling and one stone

These three golden pins range between 10 and 12 mm. The one on the left features a tiny rhinestone in a starburst and is signed Bond Boyd Ster (for sterling silver the favourite material for this renowned Canadian company). I believe the framed stone in the centre tie tack is lapis lazuli, I believe, while the cirles design of the one on the right is an appealing classic. All in great shape. Cross listed in Men's and Women's markets..
