💙 LAB-GROWN vs NATURAL SAPPHIRE — CAN YOU TELL?
These two sapphires look nearly identical. One grew in the earth over millions of years; the other in a lab in weeks. Both are real corundum — same chemistry, same crystal structure.
The differences show up under magnification: natural sapphires carry tiny inclusions from their formation, while lab-grown stones may show curved growth lines or gas bubbles.
Lab-grown isn't "fake" — but it should always be disclosed, and it's typically valued much lower than a natural stone of the same size and quality.
That's exactly what professional testing is for.
