This is a unique hand-formed and hand painted ceramic Bayes' theorem necklace made by Surly Amy at Surly Ramics. This necklace has one of our small size pendants.

"In probability theory and statistics, Bayes' theorem (alternatively Bayes' law or Bayes' rule) is a result that is of importance in the mathematical manipulation of conditional probabilities. It is a result that derives from the more basic axioms of probability." ~wikipedia

*PLEASE NOTE I make these in small batches so the necklace you receive may vary slightly from the one in the photo. The color, size and style will be the same but the glaze effect will settle slightly differently from piece to piece.

Great on men and women! I have posted a few photos of Surly Mary wearing a similar size and shape piece.

We stamp every piece on the back for authenticity so you know you're getting an original, high quality, artist made, Surly Ramics design.

The pendant is approx. 1.75" in diameter and has an 18" super soft black faux suede cord. ****************I will be happy to add a longer cord if you let me know via message to seller during checkout. Please let me know if you want the cord to be 20", 22", 24" or 26". :)******************

We offer chains and other color cords as an option for our pendants. You can go to the chain section in my shop and purchase them separately. If you buy a chain or other cord I still include the black cord with the pendant as well in case you want to switch back and forth. • Click here to pick out a chain or other cords:

The necklace comes packed in a pretty little black box and is perfect for gift giving. (even if the gift is for you!)

You can find out more info about Surly Amy (YAY!) and Surly Ramics and see our other designs and lots more photos at
