Though I may not want a live snake around me, I definitely have a penchant for snake jewelry in any form!!! It's a motif throughout the history of jewelry, from ancient times to today. 

I sourced this vintage 18K cobra ring here in California. The red and green enamel pattern is such a statement, and it perfectly compliments her fierce face.

This is not a one-of-a-king ring, though that doesn't bother me, as it's still very unique. In my research I came across the same style in a couple different color ways. I also found this exact ring on 1st Dibs for $2850! 

It fits about a size 7, though your local jewelry can certainly size it for you. 
The ring weighs 12.3 grams.
