Diamond is  the King of Gems. It is one of the most powerful stones. Diamonds are crystalline forms of carbon and are the hardest stones known. It is supposed to be the most powerful when combined with other gemstones. 

Diamond is the ultimate gemstone, having few weaknesses and many strengths. It is well known that Diamond is the hardest substance found in nature, but few people realize that Diamond is four times harder than the next hardest natural mineral, corundum (sapphire and ruby). But even as hard as it is, it is not impervious. It has a broad color range, high refraction, high dispersion or fire, very low reactivity to chemicals, rarity, and of course, extreme hardness and durability. Diamond is a polymorph of the element carbon. 

Usage:  It is said to signify purity and innocence. Has always been associated with strength and good luck. Gives calm sleep and takes away nightmares. Reflects light and thought and will absorb all energies, both positive and negative. It focuses on the brain, takes away blocking and strengthens the brain function. A stone for peace. It can help you achieve material wealth and prestige
