Vintage Mismatched Silver Snap Clasp Earrings

Our grandmother did love to mix and match similar but uniquely different items like these earrings. One is plain, with rounded edges and a grip inside the ear lobe pincher. The other has one side with pattern and the edges are square. Their snapping mechanisms are also a little bit different. 
 
Where and when they were purchased is unknown. We inherited them from our grandmother. They are unmarked but tested positive for silver using the acid test.
 
Note: Photos were hard with the lighting showing darker areas where there are none.
 
Both sit about 1” below the earlobe. Each is 1 1/2” long and 1/4” thick. 
Approx. 1 oz as a pair.
