Do Lab Diamonds Sparkle?
Yes, they absolutely do. Lab-grown diamonds have the exact same structure as natural diamonds. Same brilliance, same fire, same hardness. If a natural diamond sparkles, a lab one will too , because at the end of the day, they’re made of the same thing: carbon. The sparkle doesn’t come from where the diamond was formed, it comes from how well it’s cut. A good cut brings out the light, the life, the shine. So if you're looking at a properly cut lab diamond, it’ll catch the light in just the same way as one pulled from the earth.
Do They Get Cloudy Over Time?
No, lab diamonds don’t get cloudy. This is a common worry, but it comes from mixing them up with things like cubic zirconia. CZ can scratch and lose clarity with wear , diamonds don’t. Whether it’s grown in a lab or mined, a diamond stays clear because of its hardness and structure. If your diamond ever looks a bit dull, it's probably just surface buildup from soap or lotion. A quick clean brings the sparkle right back.
Cloudiness isn’t something that happens to real diamonds unless you’re dealing with internal flaws, and even then, it’s something you'd spot upfront , not something that develops later.
So Where Does the Confusion Come From?
Honestly, it’s mostly because people hear the word “lab” and think “fake.” But lab-grown diamonds aren’t imitations. They’re not cubic zirconia, not moissanite, not knock-offs. They're real diamonds, just made with technology instead of time. Moissanites and CZ might look similar for a moment, especially under bright lights, but they behave differently. CZ goes dull. Moissanite throws off rainbow flashes that can look too flashy in certain settings. A lab diamond reflects light like a natural one , clean, sharp, with that crisp white sparkle.
Final Word
If you’re worried a lab diamond won’t shine or will fade with time, don’t be. They’re real diamonds, and they’ll hold their sparkle for life. The key is to choose a stone that’s well cut and clean it every now and then , just like you would with any fine jewelry.
