Only an exceptionally small fraction on the diamond ore contains actual diamonds. The ore is crushed, during which care is needed to not demolish larger diamonds, and afterwards sorted by density. Today, diamonds are located during the diamond-loaded density portion with the help of X-ray fluorescence, and then the final sorting actions are accomplished by hand.
Utilizing probes for instance polarized light-weight, photoluminescence, and cathodoluminescence, a series of growth zones is often identified in diamonds. The attribute sample in diamonds in the lithosphere will involve a nearly concentric series of zones with quite slender oscillations in luminescence and alternating episodes exactly where the carbon is resorbed through the fluid after which you can grown yet again.

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」。
