与空气接触很容易被氧化而生成三氧化二铁（铁锈），典型的例子是，“美国白麻”花岗石；二是石材在切锯、磨抛、搬运、安装、清理和使用时有含铁物质残留、吸附和浸人石材的表面层，以后逐渐扩散和氧化，产生锈黄斑。*典型的例子，如用强酸清洗水泥斑会将碰到的铁质溶解带人石材微孔；又如与石材接触的生锈的铁器会因雨水等的传递将石材染成锈黄色：有机色斑：其它的含色素的物质也会污染石材，典型的如捆绑和包装石材的草绳、纸板箱等，受潮或打湿以后黄色素溶出渗入石材微孔形成黄斑。东丽液压泵全新A10VSO28DFR/31L-P

一般来讲，同一种花岗石石材根据石材荒料的品位可分为若干个等级，如将军红就根据荒料的来源不同分为C等不同的等级。相同品种的花岗石不同的等级之间石材的质量和价格相差非常悬殊，所以，石材的分级在石材选购中十分重要。区别不同等级的石材*有效的办法是比较，单独观察同一等级的石材很难看出其优劣来，但是把不同等级的石材放到一起就很容易区分出孰优孰劣。故当你确定选购某一种花岗石石材后，更多比较几家同种的石材，看看该种石材有没有分级，选购材质较新鲜、颜色较鲜艳、结构较致密的等级。
