How Biron Diamonds are made

---

Our Biron Laboratory Grown Diamond will dazzle and shine with the same chemical, physical and optical properties as a mined diamond. 

Before we talk about how laboratory grown diamonds are made, it’s important to understand how mined diamonds are formed as the processes are extremely similar – only one happens naturally while the other occurs in a laboratory.

Geologist believe mined diamonds were formed deep within the Earth, between 1 billion to 3 billion years ago. While they don’t know exactly how those diamonds came to be, they believe the process started with carbon dioxide that is buried roughly 100 miles beneath the Earth’s surface. The carbon dioxide is exposed to heat and put under extreme pressure. The diamonds are then transported from deep within the Earth’s core to the surface by way of volcanic explosions. 

Diamonds can be classified into 4 types: 1a, 1b, 2a, 2b. Diamonds are classified according to the level of their chemical impurities. Type IIA mined diamonds make up 3% of mine diamonds. Type IIA diamonds are considered the purest form of diamonds. They contain no or very little impurities and are considered the most rare and valuable type of diamonds. They contain a very little amount of nitrogen, so they don’t easily absorb short wave light. They are colourless and are almost transparent. Lab grown diamonds are classed as type IIA diamonds.

There are two processes for producing lab grown diamonds – High Pressure, High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

CVD diamonds are grown from a hydrocarbon gas mixture in the chemical vapour deposition method. CVD diamonds begin as a thin slice of diamond seed, which is often a HPHT produced diamond. The diamond seed is placed in a sealed chamber and heated to around 800 degrees Celsius. 

Over the next 10 to 12 weeks seeds go through various processes. The chamber is filled with a carbon rich gas, pressure and temperature create an environment that allows carbon atoms to break down and rain upon the seeds. As weeks go by, atom by atom, layer by layer, the seeds transform into Biron rough diamonds. Biron Laboratory Grown Diamonds acquire the same chemical, physical and optical properties as mined diamonds.

The rough diamonds are then cut and polished to exacting standards of high tech labs creating a beautiful bright Biron Laboratory Grown Diamond and is then laser inscribed by ADGL for added disclosure and identification. The Biron Laboratory Grown Diamond is then ready to be set into a stunning piece of jewellery for you to love and enjoy.
