Lab-Grown vs. Natural—How to Choose in 2026
If you are shopping for an engagement ring in 2026, you are likely already asking the big questions about sustainability and origin. You’ve heard the debate about Natural vs. Lab-Grown Diamonds.
But when it comes to Moissanite, the conversation is different.
At La Pretti, we believe in radical transparency. Many customers ask us: "Do you sell natural Moissanite?" or "Which is better?"
The answer might surprise you. Today, we are clearing up the confusion, exploring the cosmic origins of this gemstone, and explaining why Lab-Grown Moissanite isn't just the better choice—it is effectively the only choice.
Origin Story—Born from the Stars
To understand why we grow Moissanite in a lab, we have to look at where it was found.
In 1893, a French scientist named Henri Moissan was examining rock samples from a meteor crater in Canyon Diablo, Arizona. He discovered microscopic particles of a new mineral that sparkled more brilliantly than diamonds.
This mineral was Silicon Carbide (SiC), later named Moissanite in his honor.
Here is the catch: Natural Moissanite is incredibly rare. It is not formed naturally on Earth; it arrives on meteorites. The crystals found in nature are microscopic—far too small to be cut into an engagement ring.
2026 Reality: If you see a jeweler claiming to sell Natural Moissanite in 2026⚠️BE VERY CAREFUL⚠️. Virtually 100% of all gem-quality Moissanite on the market today is lab-created.
Why Lab-Grown is the Superior Choice
Since natural Moissanite is unavailable for jewelry, scientists spent a century perfecting the recipe to recreate it. The result? A gemstone that is chemically, physically, and optically identical to the meteorite crystals—but better.
Here is why La Pretti Moissanite is the ultimate 2026 gemstone:
1. Unmatched Clarity (4H Factor)
In nature, minerals are subject to chaos. They have inclusions, clouds, and cracks.
In the lab, we control the environment. La Pretti uses the premium 4H Silicon Carbide polytype. This allows us to grow crystals that are structurally perfect, resulting in stones that are almost always VVS1 to Flawless clarity.
2. Color Control
Early lab-grown Moissanites from the 1990s often had a yellow or green tint.
In 2026, technology has advanced. La Pretti stones are categorized as Top Colorless (D range), meaning they look icy white and crisp, indistinguishable from a top-tier diamond to the naked eye.
3. Ultimate Ethical Choice
Conflict-free is a buzzword, but Lab-Grown Moissanite defines it.
-
No Mining: No massive holes in the earth.
-
No Displacement: No communities removed from their land.
-
Low Carbon Footprint: Growing a crystal takes a fraction of the energy required to mine a diamond.

How to Choose Quality in 2026
Just because it is lab-grown doesn't mean all Moissanite is created equal. Cheap overseas production can result in cloudy stones or the oil slick effect.
When choosing your Moissanite for 2026, look for the La Pretti Standard:
-
Cut: Moissanite is doubly refractive (it bends light twice). It requires a specialized cut to prevent it from looking "blurry." We hand-cut our stones to maximize fire without losing crispness.
-
Certificate: Always look for a GRA or equivalent certificate of authenticity that guarantees the stone is Silicon Carbide, not cubic zirconia or glass.
-
Polish: A high-quality polish ensures the stone resists oils and dirt, keeping that disco-ball sparkle longer.
A Star on Your Finger
While you cannot buy a ring made from a meteorite (unless you are a billionaire collector), Lab-Grown Moissanite offers you the next best thing: Stardust recreated by science.
It is the perfect marriage of nature’s inspiration and human innovation.
At La Pretti, we are proud to offer stones that honor Henri Moissan’s discovery while providing a sustainable, brilliant future for your love story.
