This piece was inspired by the Vulcan amulet featured in Star Trek: Beyond. A token of Spock's affection for his beloved, Lt. Uhura, the Vokaya pendant became a lifesaver.
This piece is meant to be part of a set with the "Vulcan Amulet Setting." If you'd like the "stone" of your Vulcan amulet to be a different material from the setting, here is where you would purchase the setting.
The "stone" is listed here: https://www.shapeways.com/product/H38WTP4S8/star-trek-vokaya-stone-for-vulcan-amulet
(Alternatively, you can fill the setting with a stone found elsewhere!)
