古代印章材料，以铜为主，兼用金、银、玉、石等材料。铜质印章因其质具有延展性，以铜铸印，其文古朴雄浑；以铜镌印，其文劲健有神。金、玉因其材贵重，所传甚少而弥足珍贵。取金制印，价值贵重。但纯金印少见，常有鎏金印，皆官印。银质腻刀，则印文柔媚，常见小型银印，玲珑可喜，多为私印。玉温润有光泽，质细密而硬脆。玉印所传甚少，今可见者百余方而已。 6park.com
古代玺印除了玉质之外，还有玛瑙、水晶、绿松石、煤精石、琥珀等。战国、秦、汉时代，秦包括秦始皇统一前后，汉涵盖了两汉魏晋南北朝时期。玉石、或水晶、或玛瑙，材料很珍贵。篆刻艺术特殊，玉的质地比较坚硬，与铜、金、银等金属的质地有别，金、银、铜印或铸或凿，而玉印只能用碾，极为细致。
战国古玺无论官玺、私玺，质地大都是铜质，间有银和玉，印材选用并无定制。而到了秦代就有了严格规定，只有帝王印自称“玺”，以玉作印材。臣民用印称“印”，不能用玉。汉代规制尚“俭”皇族偶有用玉的，如“皇后之玺”和“淮阳王玺”。私印中用玉的则屡见不鲜。两汉玉印在古印中是十分珍贵稀少的一类。一般玉印制作精良、章法严谨、笔势圆转，粗看笔划平方正直，却全无板滞之意。由于玉质坚硬，不易受刀，也就产生了特殊的篆刻技法，即所谓的“平刀直下”的“切刀法”。
由于玉质的耐腐性，不易腐蚀受损，能经过漫长的岁月而较好地保留本来面目。玉质坚硬，难以受刀，白文印不可能刻得非常粗壮，粗看笔画平直规整，然全无板滞之感。这种庄重典雅、凝炼稳妥、高古秀丽的汉代玉印，给人以雍荣华贵、气息纯正的审美情趣。 6park.com
