In the heart of Pascal's laboratories, a technological marvel unfolds. Here, the intense forces of nature are recreated to give birth to our exquisite colored lab-grown diamonds. This process, known as High-Pressure, High-Temperature (HPHT), is the cornerstone of our diamond creation, yielding gems of unparalleled quality and beauty.
To appreciate the wonder of the HPHT process, one must first understand the natural formation of diamonds. Diamonds are born deep within the Earth's mantle, under conditions of extreme heat and pressure, over billions of years. They are brought closer to the Earth's surface through volcanic eruptions, waiting to be discovered and admired.
At Pascal, we emulate this natural process, but instead of billions of years, our diamonds are created in a matter of weeks. The HPHT process involves placing a small diamond seed in a controlled environment, subjecting it to conditions of high pressure and high temperature similar to those found deep within the Earth.
The diamond seed is exposed to temperatures of about 1400°C-1600°C and pressures of approximately 5-6 GigaPascals. Under these extreme conditions, the carbon atoms in the diamond seed start to arrange themselves in a crystal structure, causing the diamond to grow.
But how do we introduce color into our lab-grown diamonds? This is where the art meets science in the HPHT process. Specific elements are added during the diamond growth process that integrate into the crystal lattice structure of the diamond, giving it its unique color. For instance, nitrogen can create yellow or orange hues, while boron can create blue shades.
Throughout this process, we maintain strict control over the growth conditions, allowing us to produce diamonds of exceptional quality, consistency, and color. Our rigorous quality checks ensure that every Pascal diamond meets the highest standards of clarity, cut, carat, and color.
The HPHT process is more than a method; it's a testament to Pascal's commitment to innovation, quality, and sustainability. By recreating nature's marvel in our labs, we offer a sustainable alternative to mined diamonds without compromising on the beauty or quality. Every Pascal colored lab-grown diamond is a symbol of this commitment—a blend of scientific precision, technological innovation, and artistic vision.
At Pascal, we're pushing the boundaries of what's possible, harnessing the power of pressure to transform carbon into vibrant, lab-grown diamonds. High pressure, high temperature, high quality—that's the promise of the HPHT process at Pascal.
