CVD Diamonds or HPHT Diamonds? A Complete Guide
Lab-grown diamonds are everywhere right now, and honestly, it makes sense. They’re real diamonds, but without the baggage of mining — which means they’re a much more sustainable and ethical choice. If you’ve been doing a little digging, you’ve probably bumped into two terms that keep popping up: CVD diamonds and HPHT diamonds . At first, they sound super technical and science-y, right? Here’s the thing: both CVD and HPHT are just different ways of making a real diamond. Same sparkle, same hardness, same chemical makeup as the ones pulled from the earth. The big difference ? It’s how they’re grown, and those little details can affect things like their appearance, price, and even how jewelers spot the difference under a microscope. What Are CVD Diamonds? CVD is a process in which a solid piece of atom is placed in a vacuum chamber filled with carbon-rich gases. When these gases are heated, the carbon atom seeds are deposited layer by layer, and ev...
