How lab diamonds are made
Every diamond has a story. We believe that knowing the origin of your diamond makes it all the more meaningful. Here’s how your lab-grown diamonds are created with care through cutting edge technology that mirrors the same natural conditions under which diamonds form deep within the earth:
HPHT (High Pressure, High Temperature)
The first method is called High Pressure, High Temperature (HPHT). In this process, a small diamond seed is surrounded by carbon and exposed to intense heat and immense pressure, recreating the same forces that occur naturally beneath the earth’s surface. Over time, the carbon crystallises around the seed, growing into a diamond. HPHT diamonds are strong and durable, though they sometimes carry a subtle yellow or blue tint depending on the growth conditions.
Chemical Vapor Deposition (CVD)
The second method is known as Chemical Vapor Deposition (CVD). A small diamond seed is placed inside a vacuum chamber filled with carbon-rich gas. When the gas is heated into plasma, carbon atoms separate and gently settle onto the seed, growing the diamond layer by layer. This process gives greater control over purity, often resulting in diamonds that are beautifully white, with fewer inclusions and exceptional clarity.
Why Love Hesed Diamonds Are Mostly CVD
At Love Hesed, we choose to work mostly with CVD diamonds. This method not only creates stones of remarkable brilliance and purity, but it also requires less energy than HPHT, making it the more sustainable and environmentally friendly option. It is a choice that reflects our ethos of sustainability and responsible sourcing.
