Usually, Mexican chess pieces have a unique and interesting range of materials, from unusual stone-like Aztec Malachite Chess to Camel Bone Chess. Some sets are made with resin or alabaster in order for them not only to look good but also to last longer than most other types. There are even soapstone chess pieces (which feel more like ceramic)and Jade available if you’re looking beyond just resin-based options which can easily get dirty quickly.
