鑽石用於珠寶,因為經過專業切割後,它們會以令人愉悅的方式閃耀和反射光線。金剛石是一種具有高熔點的硬質材料。由於這些品質,金剛石是一種特別有用的切割工具,如用於切割磚塊和混凝土的金剛石圓盤所示。鑽石用於製造重型鑽頭,用於在石油勘探業務中鑽穿岩石。這可以使鑽頭在更長的時間內保持更鋒利。

除了硬度之外,鑽石還具有令人印象深刻的化學、物理和機械性能組合:

  • 硬度
  • 低摩擦係數
  • 高導熱性
  • 高電阻率
  • 低熱膨脹係數
  • 高強度
  • 從紫外線到紅外線的廣泛光學透明度
  • 耐化學腐蝕
  • 生物相容性

鑽石是由碳製成的

它具有碳同素異形體結構。術語“同素異形體”是指元素可以存在的許多結構。石墨是金剛石的近親,同樣完全由碳組成。另一方面,石墨含有鬆散堆積的碳原子,使其更軟、更脆。

鑽石的晶體結構

鑽石的晶體結構。鑽石的原子排列稱為晶體結構,它由重複排列的密集排列的原子組成。由於這種排列方式,金剛石是一種很難破碎的高硬度金屬。

金剛石結構與結合

結合和鑽石的結構。金剛石的分子結構是巨大的。每個碳原子和四個其他碳原子之間存在共價鍵。因為共價鍵非常強,分離鑽石中的原子需要很大的能量。金剛石的結構由許多共價鍵組成,具有很高的熔點和沸點。鑽石不帶電,因為它們不含電子或離子。

鑽石具有天然光澤,使其閃亮

鑽石具有固有的光澤,使它們看起來閃閃發光。鑽石具有結構均勻的原子,使它們能夠分佈所有顏色的光。這就是賦予鑽石閃爍和閃亮外觀的原因。

最堅硬的天然物質是鑽石。鑽石用於超過 70% 的工業應用,並且對商品的需求一直在增加。天然鑽石由碳晶體組成,碳晶體在地球表面以下約 100 英里的極端溫度和壓力下生長。它通常含有 99.95% 的碳。一種或多種微量元素(不屬於鑽石基本化學成分的原子)可以佔剩餘的 0.05%。金剛石具有等距晶體結構,這意味著碳原子在所有方向上都以相同的方式連接。石墨是另一種僅包含碳的礦物,具有根本不同的生成機制和晶體結構。結果,石墨很軟,可以用來寫字,而鑽石很硬,只能被另一顆鑽石劃傷。如果這些特徵都不存在,鑽石可能只是另一種礦物。另一方面,鑽石受益於化學成分、晶體結構和創造過程的獨特組合,賦予它們獨特的特徵。

Nissan, David and his team were extremely accommodating, understanding and patient with our purchase. They took the upmost care to find the best solution for our needs and went above and beyond normal ‘customer service’ standards. I have absolutely no qualms recommending their products and services. Both were absolutely flawless. I will continue to sing them praises and will most definitely purchase from them again in the future. Thank you again!

Bought a beautiful stone here for an engagement ring. I was a little apprehensive since you’re buying something unseen. But Cid made it easy. In fact, Nissan, the owner also gave a call to make me more comfortable. They sent me the stone to take to a local jeweler with only my Amex in case I bailed on them.
