Vintage sterling silver, clear paste rhinestone earrings with screw backs - two designs to choose from

Fabulous antique / vintage Edwardian sterling silver and rhinestone screw back earrings. I have two slightly different designs available, each pair with slight differences in size, arrangement and stamps on the silver.

They both have a main panel that is absolutely stunning with sterling silver claw / prong settings, set with (what I assume are) rhinestones in a classic floral arrangement. It is possible they are some sort of gemstone like rock crystal or cubic zirconia, but I am listing as glass as my assessment. 

Pair 1 - This pair has a floral panel and has two diamante above and sits on the earlobe. These test as sterling silver and are stamped with 'patent' and then the patent number on the reverse of the main panel.

Pair 2 - These earrings also have the floral paste panel as a dangle drop, but this time with one further paste stone above leading up to the screw fastener. These also have the patent number stamped on the back of each and also the silver stamp (SIL) on the back of each screw fastener.

The earrings are all in very good vintage condition - please examine photos carefully for minor signs of age, eg very faint yellowing of some of the pastes.
