How to Know if Your Stones Are Lab Grown
Ever stared at a diamond and wondered—is this straight from deep underground or born in a lab? You’re not alone. With lab grown diamonds becoming more common, telling them apart from mined stones can feel tricky. Whether you’re exploring, making a conscious choice, or curious about what’s already on your finger, a little insider know-how goes a long way.
What Is Lab Grown, and Why Should You Care?
Check out our blog that dives deeper into What is Lab Grown, The short version is that lab grown diamonds are, quite literally, diamonds—same chemistry, same dazzle. They’re created in high-tech labs using methods like HPHT (High Pressure, High Temperature) or CVD (Chemical Vapor Deposition). These processes mimic nature, minus the millions of years and heavy mining. Want the science scoop? Check out GIA or IGS.
Why it matters is simple: lab grown gems are a cleaner, more ethical option—and often cost less. You get all the brilliance with a lighter footprint. No wonder they’re easy to mix up.
So… How Can You Tell If It’s Lab Grown?
- Check for Laser Inscriptions
Most lab grown diamonds have a tiny inscription on the girdle (that thin edge). It may say “lab grown” or show a cert number. Grab a loupe and take a peek—or swing by Quantum Qarat in Phoenix and we’ll help. - Always Ask for Certification
Legit stones come with papers (IGI or GIA). “Natural” means mined; lab reports state it outright. - Ask Where It Came From
A reputable jeweler shares sourcing details without hesitation. If they dodge? Time to walk away. - Get a Pro to Check It Out
Tiny growth features—metallic specks, unique fluorescence—show up under a microscope. We offer one-on-one inspections so you know exactly what you’re wearing. - Use a Diamond Tester—With Caution
Basic testers tell diamond vs. moissanite, not lab vs. natural. Advanced models help, but none are perfect.
Quick Tips to Keep in Mind
- Price isn’t foolproof—top-tier lab stones can rival natural costs.
- Still unsure? Get a trusted second opinion.
- Go with transparency. A jeweler open about sourcing—like us at Quantum Qarat—will walk you through the facts.
