CVD diamonds are created through a process known as Chemical Vapor Deposition, one of the two processes of making lab-grown diamonds. The process involves breaking down natural gas such as methane into carbon atoms, making a diamond. The other method is High-Pressure High Temperature (HPHT). C...

Labgrown diamonds, also known as synthetic diamonds , are diamonds produced in a laboratory by simulating natural processes underground. These diamonds are very similar in chemical and physical properties to naturally occurring diamonds, but they are artificially created. Here is some basic information ...
Chemical Vapor Deposition Lab Diamonds CVD diamonds grow when a thin piece of diamond seed is placed in a vacuum chamber filled with a carbon-rich gas mixture (typically methane and hydrogen) that’s heated to break down the gas molecules. Carbon atoms settle onto the seed, building layer by...
Physical vapor deposition (PVD) differs from chemical vapor deposition (CVD) in the sense that the former process only relies on physical processes to transfer the coating materials into the gas phase. The latter commonly uses precursors that are already gaseous. CVD coatings can be obtained in ...

This is how they make tungsten light bulb filaments. Other possibilities for iridium crafting include carving it like a stone with diamond or cubic boron nitride abrasive; electroplating with one of its many colorful salts dissolved in a liquid; or performing chemical vapor deposition using iridium ...
Yes, physical methods like physical vapor deposition (PVD) can apply coatings without chemical processes, often used for non-conductive materials. 7 Can plating improve electrical conductivity? Yes, certain metals used in plating, such as gold and silver, can enhance the electrical conductivity of ...
Here’s everything you need to know about diamonds made in a lab, according to an expert. Plus: whether or not you should buy a lab-grown diamond engagement ring.
