I could not speak more highly of Darren. He was very insightful and helpful as I selected and purchased my Fiancé's wedding ring. He made the entire process easy, fun, and insightful. I would recommend Carbon Diamonds to my family and friends in a heart beat!

When my now husband and I were shopping for an engagement ring we searched at all the usual higher end shops. I wanted something different and not cookie cutter which is hard to find. We heard about Darren and decided to meet with him to discuss our wants. From the first appointment we knew he was the guy!

Darren is a wonderful person, and incredible to work with. He helped me with finding the perfect engagement ring for my fiancé all the while educating me about diamonds as well as the diamond industry. His transparency about how everything works was incredibly refreshing, and I would highly recommend Carbon Diamonds to friends and family.

I normally don’t do the review thing but the customer service was everything you dream of when having something custom made. Darren and Tanner did a great job on my wife’s custom dream ring! Not only did they educate us on the different qualities and shapes of diamonds they also taught us about the 4 C’s! I’m referring these guys to all my friends! Thank y’all for helping us make our dreams come true!

FAQs

Yes! Carbon Diamonds offers both Lab-Grown Diamonds and ethically sourced Natural Diamonds—and they’re all 100% real. Lab-grown diamonds share the exact same carbon structure as natural diamonds, making them chemically, physically, and visually identical. Natural diamonds, on the other hand, are formed deep within the Earth over millions of years. Both are cut, polished, and certified using the same rigorous standards, ensuring brilliance, durability, and timeless beauty.

Choosing between a Lab-Created Diamond and a Natural Diamond comes down to personal preference, values, and budget. At Carbon Diamonds, we proudly offer both—ensuring every option is beautiful, ethical, and responsibly sourced.

  • Cost – Lab-Created Diamonds are often more affordable because they’re produced in a controlled environment. Natural Diamonds, especially rare sizes and colors, may carry higher value due to their uniqueness.
  • Ethics & Sustainability – All of our diamonds, whether lab-grown or natural, meet strict standards for ethical sourcing. We believe luxury should never compromise human rights or the planet.
  • Quality & Beauty – Both lab-created and natural diamonds can achieve exceptional color, clarity, and brilliance. Lab-grown stones are created with consistency, while natural diamonds carry one-of-a-kind character formed by nature.

Ultimately, the “better” diamond is the one that best reflects your story, your values, and your style.

Our diamonds come from two trusted sources: advanced laboratories and vetted ethical mining partners. Lab-Grown Diamonds are created with cutting-edge technology that replicates the natural process of diamond formation, while our Natural Diamonds and Gemstones are sourced only from suppliers who meet strict ethical and environmental standards. Whether lab-grown or mined, every stone we offer is chosen for its quality, sustainability, and integrity.

Absolutely! We welcome you to explore our Dallas, TX showroom and view our collection of Lab-Grown and ethically sourced Natural Diamonds and Gemstones in person. Walk-ins are welcome, but we recommend scheduling an appointment so our diamond experts can provide you with a personalized consultation and answer all your questions.
