The outer face is engraved with integers and hatch marks, as well as extra marks for the mathematical constants pi and e. The ring can be customized. It can be made of gold, platinum, or bronze, and can also be made to any size. For these custom metal requests, please contact me for a quote. For a ballpark estimate, scale by the relative value of (metal X)/(silver).I have toyed with the idea of inlaying precious stones, perhaps at pi or e, or at some number that is significant to you, personally. If that appeals to you please feel free to message me. The pictured ring is size 10 and I have a limited number in stock. However, any size can be ordered. Please allow 2 weeks for sizes other than 10. For instructions on how to perform calculations, see wikipedia, "Slide Rule". I hope the eventual recipient enjoys this ring as much as I enjoyed making it.
