阿富汗玉又叫碳酸盐质玉，主要成分方解石，因此也叫方解石玉。少部分内部含有透闪石，硬度较高。阿富汗玉通常是指一种彩色碳酸盐玉石的总称，玉行内简称“阿料”，是一种比较常见的玉料。
和田戚猛族玉主要成分为透闪石，所以经常高弊有人拿阿富汗冒充和田玉来谋取不义之财。许多不法商人把汉白玉，大理岩当做低档的阿富汗玉卖，冒充阿富汗玉！虽然两者在鉴定上主要成分都是碳酸盐质玉，但是无论品质还是价值都截然不同。两者最明显的区别就是在油润度和透润度知渗上。大理石无论成分怎么相似，但是成色是始终无法与阿富汗玉相比拟的。就像钻石和石墨，主要成分都是碳，但是性质和价值确是天壤之别。汉白玉和阿富汗玉都是白色大理石,因其从汉代开始利用,白度高,似玉而非玉,故得名"汉白玉"。汉白玉经矿山开采、切片,磨光之后用作建筑材料和雕件材料。产于阿富汗的大理岩便是阿富汗玉，两者鉴定特征相似，矿物成分都是方解石。只是阿富汗玉有时看起来更细腻，层状结构更明显，常雕成玉白菜。
阿富汗玉象征着纯洁之石，颜色为白色，有玻璃光泽。阿富汗白玉是由精美的方解石和透闪石多种成分种组成，玉质优美，洁白清丽，神似新疆白玉，但价格比新疆白玉便宜。纯洁温润，有种特别的可爱气质。 阿富汗白玉玉色如凝脂，油脂光泽，精光内蕴，厚质温润，脉理坚密，水灵通透。波斯王朝在18世纪对阿发动了侵略战争，目标仅仅是阿富汗特产的珍贵白玉，阿富汗白玉中含有对人体有益的十多种微量元素锌、铁、硒、镁、....等。
难能可贵的这些元素在阿富汗白玉中异常活跃，是故经常佩戴这些微量元素很容易通过皮肤吸入人体内，从而能平衡阴阳气血的失调，使人祛病保健益寿。迎着阳光，似有玉液流动，轻敲之，清韵悠远，历久不绝，灵异神奇。阿富汗贵族家庭都不惜重金购置白玉制品，可使家中冬暖夏凉，以避免承受当地温差巨大之苦；佩玉则为贵妇最爱，以助祛病养颜；当地儿女出嫁，有能力的家庭会尽量配白玉嫁妆，以显隆重；由于白玉色泽的纯白和品相的灵异，各族宗教都争相使用白玉制作圣物，wansh98%以上居民信奉的伊斯兰教会更是珍藏甚丰， 阿富汗白玉石经过漫长的地质变化，由山顶转移沉淀到河底，它们静静地躺在珍贵水源之底，经历的千万年的滋润，变得越来越晶莹，越来越致密，成就其绝世的品质，近些年阿富汗的本来稀少水资源逐渐萎缩，民间传说认为是玉矿吸收了大量的水份，科学家对阿富汗白玉吸水一说也无法解释，白玉的物理结构厚实缜密，但也饱含水份，且不宜蒸发，甚为神奇。
