랩그로운 다이아몬드는 땅에서 자연적으로 형성된 다이아몬드가 아니라 실험실에서 만들어진 다이아몬드입니다. 합성 다이아몬드, 배양 다이아몬드 또는 인조 다이아몬드라고도 합니다.

랩그로운 다이아몬드는 고압 고온(HPHT) 및 화학 기상 증착(CVD)의 두 가지 방법을 사용하여 생산됩니다. 두 방법 모두 고급 기술을 사용하여 다이아몬드 형성의 자연적 과정을 복제하지만 훨씬 짧은 시간 내에 수행됩니다.

그 결과 랩그로운 다이아몬드는 천연 다이아몬드와 동일한 물리적, 화학적 및 광학적 특성을 가지며 일반적으로 천연 다이아몬드보다 저렴합니다. 또한 천연 다이아몬드와 관련된 광범위한 채광 및 추출 과정이 필요하지 않기 때문에 보다 환경 친화적인 것으로 간주됩니다.

그러나 랩그로운 다이아몬드는 여전히 시장에 비교적 새로운 제품이며 윤리적 의미와 천연 다이아몬드 산업에 대한 잠재적 영향에 대한 논의가 진행 중이라는 점에 유의해야 합니다.

 

고압온도 기법과 화학기착 기법

 

고압 고온(HPHT) 및 화학 기상 증착(CVD).

HPHT(High Pressure High Temperature): 이 방법은 금속 촉매 혼합물에 작은 다이아몬드 씨앗을 넣은 다음 매우 높은 압력(평방 인치당 약 150만 파운드)과 고온(약 섭씨 1,500도)에 노출시키는 것을 포함합니다. 누르다. 압력과 온도로 인해 다이아몬드 씨앗 주위에 탄소 원자가 형성되어 결국 더 큰 다이아몬드 결정으로 성장합니다. 이 과정은 원하는 다이아몬드의 크기와 품질에 따라 몇 주에서 몇 달이 걸릴 수 있습니다.

화학 기상 증착(CVD): 이 방법에서는 다이아몬드 시드 재료의 얇은 조각을 진공 챔버에 넣은 다음 약 섭씨 800도까지 가열합니다. 수소 및 메탄 가스가 챔버에 도입되고 마이크로웨이브 에너지원이 가스를 이온화하여 탄소 및 수소 원자로 분해하는 데 사용됩니다. 그런 다음 탄소 원자는 다이아몬드 씨앗에 부착되어 점차 더 큰 다이아몬드 결정으로 축적됩니다. 이 과정은 원하는 다이아몬드의 크기와 품질에 따라 며칠에서 몇 주가 소요될 수 있습니다.

두 방법 모두 물리적, 화학적, 광학적 특성 면에서 천연 다이아몬드와 사실상 동일한 고품질 다이아몬드를 생산합니다. 생성된 다이아몬드는 천연 다이아몬드처럼 절단 및 연마가 가능하며 다양한 보석 용도로 사용됩니다.

 

Lab-grown diamonds are diamonds that are created in a laboratory rather than being formed naturally in the earth. They are also known as synthetic diamonds, cultured diamonds, or man-made diamonds.

Lab-grown diamonds are produced using two methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both methods involve using advanced technology to replicate the natural process of diamond formation, but in a much shorter time frame.

The resulting lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds, and are typically less expensive than their natural counterparts. They are also considered to be more environmentally friendly, as they do not require the extensive mining and extraction process associated with natural diamonds.

However, it is important to note that lab-grown diamonds are still relatively new to the market and there is ongoing debate about their ethical implications and potential impact on the natural diamond industry.

 

High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

High Pressure High Temperature (HPHT): This method involves using a small diamond seed placed in a metal catalyst mixture and then exposed to extremely high pressures (around 1.5 million pounds per square inch) and high temperatures (around 1,500 degrees Celsius) in a special press. The pressure and temperature cause carbon atoms to form around the diamond seed, eventually growing into a larger diamond crystal. This process can take several weeks to several months, depending on the desired size and quality of the diamond.

Chemical Vapor Deposition (CVD): In this method, a thin slice of diamond seed material is placed in a vacuum chamber, and then heated to around 800 degrees Celsius. Hydrogen and methane gases are introduced into the chamber, and a microwave energy source is used to ionize the gases, breaking them down into carbon and hydrogen atoms. The carbon atoms then attach themselves to the diamond seed, gradually building up into a larger diamond crystal. This process can take a few days to a few weeks, depending on the desired size and quality of the diamond.

Both methods produce high-quality diamonds that are virtually identical to natural diamonds in terms of their physical, chemical, and optical properties. The resulting diamonds can be cut and polished just like natural diamonds, and are used in a variety of jewelry applications.

 

High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

  1. High Pressure High Temperature (HPHT): This method involves using a small diamond seed placed in a metal catalyst mixture and then exposed to extremely high pressures (around 1.5 million pounds per square inch) and high temperatures (around 1,500 degrees Celsius) in a special press. The pressure and temperature cause carbon atoms to form around the diamond seed, eventually growing into a larger diamond crystal. This process can take several weeks to several months, depending on the desired size and quality of the diamond.
  2. Chemical Vapor Deposition (CVD): In this method, a thin slice of diamond seed material is placed in a vacuum chamber, and then heated to around 800 degrees Celsius. Hydrogen and methane gases are introduced into the chamber, and a microwave energy source is used to ionize the gases, breaking them down into carbon and hydrogen atoms. The carbon atoms then attach themselves to the diamond seed, gradually building up into a larger diamond crystal. This process can take a few days to a few weeks, depending on the desired size and quality of the diamond.

Both methods produce high-quality diamonds that are virtually identical to natural diamonds in terms of their physical, chemical, and optical properties. The resulting diamonds can be cut and polished just like natural diamonds, and are used in a variety of jewelry applications.
