Higher-purity diamond wafers 5 cm in diameter show great resistance in a single route and excellent conductance in another, building the potential of employing them for quantum knowledge storage.
Diamonds are dated by analyzing inclusions using the decay of radioactive isotopes. Based on the elemental abundances, one can look at the decay of rubidium to strontium, samarium to neodymium, uranium to lead, argon-forty to argon-39, or rhenium to osmium. Those people present in kimberlites have ages ranging from one to 3.5 billion a long time, and there is usually many ages in the exact same kimberlite, indicating many episodes of diamond formation. The kimberlites on their own are much young.
The output and distribution of diamonds is essentially consolidated within the palms of some key players, and concentrated in standard diamond buying and selling facilities, The most crucial getting Antwerp, the place 80% of all rough diamonds, fifty% of all Slash diamonds and more than 50% of all rough, Reduce and industrial diamonds merged are taken care of.

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」。
鑽石的色澤會因為化學上的雜質而有所偏差。完全純正的鑽石應該是透明無色的。鑽石偏向不同的顏色會影響它的價值。絕大部分的鑽石都是因為帶有氮原子而偏黃。白鑽越偏黃，價值便越低。但是偏粉紅或藍的鑽石價格卻較高。顏色強烈偏向粉紅或藍的鑽石可能價值連城。
