Pyrite Crystal Habit

Pyrite Crystal Habit distills the pre-1900 Western European tradition of crystallographic habit plates — engraved illustrations that catalogued the cubo-pyritohedron forms of iron sulfide (FeS2). Pale brass-yellow metallic crystals with striated faces and intergrown twins sit on a slate-grey rock matrix, their luster and faint tarnish iridescence rendered with engraved precision.

This system turns that mineralogical plate into a digital language: a dark mineral-gray ground lets brassy gold dominate, monospaced indices label crystallographic axes, and engraved serifs name each specimen with period authority.

「黄铁矿晶习」提炼自 1900 年前西欧晶体习性图版的传统——那是为二硫化铁（FeS2）的立方-五角十二面体晶形编目的雕版插图。淡黄铜色的金属光泽晶体带有条纹晶面与连生双晶，安置在板岩灰的岩石基质上，其金属光泽与隐约的锖色虹彩以雕版般的精确度呈现。

本设计系统将这一矿物学图版转化为数字语言：深矿物灰的底色让黄铜金调主导画面，等宽字体标注晶体学轴向与指数，雕版衬线字体以学究般的权威为每一标本命名。
