田黄石（Field-yellow stone），简称“田黄”，产于福州市寿山乡寿山溪两旁之水稻田底下，呈黄色而得名。是寿山石品种中的珍品。广义的田黄石指“田坑石”，狭义的田黄石指田坑石中发黄色者。物理性质、工艺美术特征方面，田黄石与寿山石相近，已成为独立的印章石品种。
田黄石是寿山石系中的瑰宝，素有“万石中之王”尊号。其色泽温润可爱，肌理细密，自明清以来就被印人视为“印石之王”。数百年来田黄石极受藏家至爱，正如俗语所说：“黄金易得，田黄难求”。
早在一千多年前，我国已有人开始采集，到了明清两代田黄石更是盛名于世。许多达官显贵，文人雅士竞相刻意收集田黄石。相传清初时期皇帝祭天，神案上都少不了一方上品田黄石。因此，田黄石一直盛名不衰，身价倍增，曾有古话“一两田黄一两金”。

上图可见清晰的萝卜纹，红筋，表现十分自然，这也正是由于田黄冻的半透明感，给人直观的体现了萝卜纹，红筋的美感，由此特征为开门田黄冻石。
萝卜纹是田黄石的沁色通道，众所周知，原本是山中矿石的田黄石胚，经过溪水长期的冲刷滚动，磨圆了棱角，淘净了杂质，形成了卵形的田黄石胚胎，然后又被地表的虚土掩埋在溪谷沙石泥土的底层，在周围含铁土壤、水分及温度的浸渍与影响下，对田黄石起了沁色（自然加色）作用。这种漫长而十分特殊的沁色过程，使田黄石的色泽自然瑰丽，而肌理隐现的萝卜纹便是田黄石沁色的通道。或者说没有田黄石的萝卜纹，就不会有田黄石桔皮黄、金黄、桂花黄、熟栗黄，枇杷黄，奶黄等颜色形成的必要条件。
九叠篆，是一种非常特别的篆书，原本是一种流行于宋代的“国朝官印”字体，主要用于印章镌刻，其笔画折叠堆曲，均匀对称。每一个字的折叠多少，则视笔画的繁简确定，有五叠、六叠、七叠、八叠、九叠、十叠之分。之所以称为“九叠”，则是因“九是数之终，言其多也”。可见此田黄印章九叠篆之精美，不仅材质珍贵，工艺超绝，同时也具有极高的书法价值。
可见基座上几条红筋，其中一条红筋十分明显，再看此狮钮印章，狮子偏头回望，而古代取其谐音，寓意为：好（狮）事在后头，故而此印章寓意十分吉祥，为市场讨喜之珍品。
身为“印石三宝”之一的田黄石，呈现黄、白、红、黑等色，其中以黄色为最常见。具有珍珠光泽、玻璃光泽、油脂光泽，微透明至半透明，少数透明。硬度2.5，密度2.65-2.90克/厘米3。质地致密、细腻、温润、光洁。尤为引人注目的是其肌里隐约可见萝卜纹状细纹，颜色外浓而向内逐渐变淡，表面时而裹有黄色或灰黑色石皮，间有红色格纹。为田黄石所独有的外观特征，素有“无纹不成田”、“无皮不成田”、“无格不成田”之称。诚然，从其石质来说，仍以纯净为贵。
这件田黄颜色纯正，整体呈现冻状，有如果冻一般，润感十足，字体篆刻精美，工整，章面干净整洁，且有老朱砂红泥附着，可见此印章带着年代沧桑感，细看品相完美，十分耐赏！目前田黄价格以克计算，加上这工艺年代，其收藏价值不可估量，为市场追逐之稀有宝藏，可谓是千金易得，一宝难求。
