What are fancy yellow lab-grown diamonds?
Fancy yellow lab-grown diamonds are captivating gemstones with the same chemical and physical characteristics as natural fancy yellow diamonds, which are treasured for their vibrant hue. The main difference between the two lies in their origin: while natural diamonds are formed in nature, yellow lab-grown diamonds are created in labs that replicate the same conditions found in nature.
These lab-grown diamonds have nearly the same qualities as their rare natural counterparts. They are produced through advanced technological processes such as Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT).
They boast the same chemical composition, crystal structure, and physical properties as mined diamonds, resulting in an appearance that beautifully mirrors natural fancy yellow diamonds.
In essence, fancy yellow lab-grown diamonds offer the stunning visual appeal of natural diamonds while providing an alternative created under controlled conditions in a laboratory setting.
The striking fancy yellow color of these lab-grown diamonds is achieved by introducing trace amounts of nitrogen during the growth process. Nitrogen atoms replace some carbon atoms in the diamond’s lattice structure, resulting in a yellow hue. These diamonds are available in different shades of yellow, ranging between six color grades, from fancy light to fancy dark.
The addition of nitrogen not only gives the gemstones their distinctive color but also assists with their rapid formation and growth. Typically, diamond formation in a lab takes around a month. Still, when nitrogen is added, it takes only one week to produce such a diamond.
How are fancy yellow lab diamonds created?
Fancy yellow lab-grown diamonds are created using advanced technology replicating natural diamond formation conditions. The two most common methods for producing these gemstones are Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT). Both processes yield high-quality diamonds with the same chemical composition, crystal structure, and physical properties as natural diamonds.
Chemical Vapor Deposition (CVD) involves:
- Placing a diamond seed in a chamber with a carbon-rich gas mixture
- Heating the chamber to release carbon atoms
- Depositing carbon atoms onto the diamond seed to form a crystal
- Introducing nitrogen to achieve the fancy yellow color
High-Pressure High-Temperature (HPHT) simulates conditions deep within the Earth:
- Placing a diamond seed in a carbon-rich environment with a metal catalyst
- Subjecting the mixture to extreme pressures and temperatures
- Dissolving carbon into the metal catalyst and crystallizing it onto the diamond seed
- Adding nitrogen during the growth process for the yellow hue
For the HPHT process, scientists follow specific steps:
- Setting up an apparatus capable of generating high pressures and temperatures
- Placing a metal piece and a carbon-containing material in a capsule
- Powering the apparatus to melt the carbon material alongside the metal piece
- Allowing the molten carbon mixture to flow to a cooling chamber with a diamond seed
- Adding nitrogen atoms to the substance, which crystallizes into a yellow diamond after about a week
In the CVD method, key steps include:
- Heating a mixture of hydrogen and methane gas in a vacuum chamber at low pressures
- Transforming some hydrogen gas into atomic hydrogen for a stable diamond growth environment
- Reacting atomic hydrogen with methane gas to form a highly reactive carbon-hydrogen substance
- Incorporating a diamond seed crystal and nitrogen atoms into the gas mixture to produce a yellow diamond
