Colored diamonds incorporate impurities or structural defects that trigger the coloration, though pure or practically pure diamonds are transparent and colorless. Most diamond impurities exchange a carbon atom in the crystal lattice, often known as a carbon flaw. The most typical impurity, nitrogen, causes a slight to powerful yellow coloration depending on the type and concentration of nitrogen current.[36] The Gemological Institute of America (GIA) classifies very low saturation yellow and brown diamonds as diamonds in the normal coloration assortment, and applies a grading scale from "D" (colorless) to "Z" (light-weight yellow). Yellow diamonds of significant shade saturation or a different shade, including pink or blue, are termed fancy coloured diamonds and fall underneath a different grading scale.[36]
象徵著兩人婚姻關係的對戒,通常戴於無名指上,一個距離心臟最靠近的位置。這是由於古埃及人相信,左手無名指的血液直通心臟,因此左手無名指是最靠近心臟的地方,有「我心已許」的意思,而這就是為什麼結婚對戒戴在無名指上的原因。

碳有數種已知的同素異形體:不定形碳 ,碳奈米泡沫 ,金剛石,藍絲黛爾石 ,蠟石 ,聚合鑽石奈米棒 ,環碳石墨烯、石墨和富勒烯。在熱力學上,金剛石的穩定性低於石墨,可自發轉變為石墨,但常溫常壓下這一轉變的速度很慢,可以忽略不計,因此鑽石得以穩定存在。自然界形成的金剛石一般形成於地球內部高溫高壓的環境,後來被火山噴發等地殼構造運動帶到地表,因此許多金剛石發現在火山附近。現代工業可在高溫高壓下生產金剛石,稱為「合成金剛石」。
由於金剛石的硬度極高且導熱性極高,用於沙紙、鑽探、研磨工具之上,可以用來切削和刻劃其他物質,以及大型積體電路等散熱板上。
