I love making wax seals - for real letters, written in the moment, sealed and sent. We have an old ring with a family crest featuring this Wyvern. There silver earrings were made as part of my new 'Everyday Talisman' collection.
I've used Fine Silver recycled to take an impression from my family wax seal - which features the Wyvern - believed to be a symbol of power and strength.
These studs have more than a hint of Hogwarts about them, with a Gothic heraldic vibe too.
The earrings are made from 80% fine recycled silver with sterling silver posts and backs - I've also included plastic push on backs if you prefer them.
This is some info all about why Wyverns’ were chosen... Wyverns are the most common of the draconic heraldic symbols. They are seen almost as commonly as birds, and they are numerous in design. Since most wyverns were depicted as evil dragons in bestiaries, which were widely circulated at the time of the adoption of coats of arms, the fact that so many families adopted them as their symbol is not yet fully understood.  However, the wyvern is most notably show as a creature of valour and protection, and, as most dragons in the past, also believed to have great eyesight.  In another light, the wyvern is also a symbol of vengeance or may have been acquired threw a family member's slaying of a dragon. 
The wyvern was, most probably, believed to be a symbol of power and strength, which was important in battle. However, very little about wyvern crests and their symbolism have been recorded.
The crest, however, does represent dragon kind as it was believed in those times. Scales, a forked tong, a spiked back, and a whip-like tail make this creature quite formidable.
