Lab created diamonds are just as real as natural diamonds but offer a significantly lower price point. Produced using cutting edge technology in a laboratory setting, these diamonds boast exceptional quality, beauty, and value. Not only are they budget friendly, they also promote sustainability and ethical practices. To match our sustainable diamonds, we use sustainably sourced precious metals.

Lab grown diamonds are genuine diamonds created in a laboratory using advanced technology. They are identical to mined diamonds in every way, but they cost less and carry no ethical concerns. Just like mined diamonds, our lab created diamonds are made of carbon atoms arranged in a crystalline structure, giving them the same brilliance, durability, and timeless beauty, lattice structure.

Our lab created fancy colored diamonds are real diamonds, just like their mined counterparts. Their vivid hues are achieved through a process that mirrors how colors naturally form in mined diamonds. By introducing trace elements into the crystal structure, these diamonds take on the captivating shades we love, from delicate pinks to vibrant yellows and blues.

Lab created diamonds are not fake. They are real diamonds. Made from the same carbon crystals as mined diamonds, they share the exact physical and chemical properties. This sets them apart from simulants like cubic zirconia or moissanite, which are entirely different materials. Unlike fakes, both mined and lab grown diamonds display the brilliance and durability that make diamonds unique, while simulants can usually be spotted with the naked eye.

Our lab created diamonds are true luxury items, crafted with advanced technology and exceptional care. While they will always be valuable, they cost less than mined diamonds because they avoid the heavy expenses of mining operations. This means you can enjoy a larger, higher-quality diamond for the same budget, making our lab created diamond jewelry the smarter, more ethical way to shine.

When it comes to buying a diamond, lab created diamonds are the clear choice for those who value sustainability, ethical practices, and affordability. Both lab grown and mined diamonds are real, so your decision comes down to personal preference. With After Diamonds, you can feel confident in choosing luxury and quality at a better value. The most important thing is selecting jewelry that speaks to your heart and fits your budget and with lab created diamond jewelry, you truly can’t go wrong.
