Vintage sterling silver floral earrings: Set of two pairs, one signed

The shimmering charm of yesteryear! Here are two pairs of nicely detailed screw-back earrings that likely date back to mid-century. The larger blooms are 3/4 inch in diameter and marked Sterling, while the dainty roses are about 1/3 inch in diameter and are marked Bond Boyd (renowned Canadian maker) and Ster. Combined weight of about 11 grams. Both pairs are in nice shape, with some patina. The screw backs of the larger pair are quite malleable, but do not appear to be in fragile unless manipulated roughly.
