5-26-09 I don't see a sterling mark on this but I think it is sterling. This is for the Gemini, you or a friend. Gemini is the twin as you all know but they are also known to have doppelgangers of which can have a better life or a worse one. This gives you the chance to take a glimpse of that and decide if you want to switch or not.
This also allows you to travel astrally with more ease and that is for any of the signs.
An odd one for sure but still a great metaphysical item.
