What Does Lab-Grown Mean?
The same beauty, created differently

LumGem lab-grown gemstones are created using advanced technology that recreates the conditions in which gemstone crystals form. They have the same essential chemical composition, crystal structure and optical properties as their natural counterparts—bringing vivid color and brilliance at a more approachable price. Just like natural stones, lab-grown diamonds and gemstones can also be submitted to independent labs such as GIA or IGI for identification or grading.

Real Pieces. Real Moments.

  1. Tim D.Verified Buyer

    We were very impressed by not only the quality (cut and clarity) of the gemstones but also the packaging and presentation. We’ll be back for future occasions!

    Purchased: Emerald

  2. Richard A.Verified Buyer

    Presentation meets quality at a fair price. Couldn’t recommend more highly. My usual go-to for lab diamonds was another jeweler, but when ordering this beautiful emerald and diamond ring I went with LumGem. Particularly impressed with the presentation and the surprise in the box.

    Bought a sapphire with diamonds on either side of it engagement ring. Absolutely stunning from every angle. As beautiful as anything I’ve purchased for my wife during a long marriage. Again, beautiful, compelling, sparkling, classy in every way.

Lab-grown gemstones are chemically, physically, and optically identical to mined gemstones — grown in controlled environments that replicate the conditions under which gems form naturally, just without digging them out of the earth. To the eye, and to any gemologist, they're the real thing.
Yes. Because lab-grown gemstones share the same crystal structure and hardness as their mined counterparts, they wear, sparkle, and hold up exactly the same way over daily wear.
Growing a gemstone in a controlled environment is more efficient than mining one from the earth, and we sell directly to you rather than through multiple middlemen — savings we pass straight on to you, without cutting corners on quality.
If something isn't right, our 30-Day Return policy gives you time to make sure your piece is the one.
It has the same beauty and chemical composition, with a modern creation process.
