钻戒是由指圈、爪镶、以及钻石组成的。 。那么在钻戒中最重要的部分则是钻石。关于钻石有很多的美丽传说，钻石的英文名称Diamond，来源于希腊文金刚一adams，意为“无可征服”，然而当时，此词用来指铁等坚硬的金属，之后又泛指硬度比铁大得多的蓝宝石。随着人们对宝石的不断认识，才把diamond专指钻石。古希腊人相信钻石是陨落到地球上的星星碎片，甚至有人认为钻石是天神滴落的眼泪;人们也一度认为钻石是由天水或天露而来。在梵文中钻石一词即为雷电之意，借以表达钻石由闪电而生的信仰。直至今日现代科学的发展才告知人们钻石并不是由天而降，相反是破地而出的。古人还相信钻石会生小钻石，连著名的科学家波义尔(R.Boyle，1627-1691)也相信此种说法。在17世纪，葡萄牙的探险家认为“钻石在接近地表处生长2-3年可长成”，并以矿工为何若干年再返回老矿区仍可采到钻石为例证实这一观点。
