The Pi Symbol Medallion features the Greek letter pi in bold 3mm relief, the mathematical constant that defines the relationship between a circle's circumference and its diameter and has captivated mathematicians for millennia. An elegant symbol for anyone who finds beauty in numbers. For the mathematician, the scientist, the engineer, or anyone who spent enough time with numbers to appreciate what pi represents. This medallion is a way to hold that elegance in metal, a piece for the person who thinks in equations and appreciates precision.

Every Pi Symbol Medallion begins as a cast billet of raw Silver .999 Fine, Copper, or Nordic Gold (CuAlZnSn), milled down through a rough clearing pass and then a fine detail pass to reach its full 3mm relief. What sets the finishing step apart is the weight: each 35mm piece is placed on a scale and precision cut until it hits exactly 2.5oz, not an approximation. From there it's optionally hand stamped with up to 16 characters and sealed in clear lacquer. Free US shipping, 5-7 business days to complete.

Precision on weight is the differentiator here: cast, machined, individually weighed, and cut to an exact target, every single piece, a level of control most makers simply don't apply. The shop stays just as disciplined about scope, only cast and CNC-machined metal medallions get made here, which means every improvement in the process serves this one craft rather than being divided across a wide catalog.
