The “Flame Fusion” Myth: This 100-Year-Old “Fake” Ruby Is Still Fooling Buyers, How to Spot a Verneuil Synthetic Ruby.

For more than a century, flame-fusion rubies have been sold as “real rubies.” The material is real corundum (aluminum oxide) with chromium, so it looks and tests like ruby.

Natural Ruby vs. Lab-Grown: Look for “Silk,” If Your Ruby Is Perfectly Clear, It’s 100% a Lab-Grown Fake, A Gemologist Explains.

Most people think a ruby should be crystal clear. In nature, it rarely is. Natural rubies almost always carry tiny internal features—especially fine “silk,” the trade name for rutile needles—that prove they grew in the earth. When a ruby is perfectly clear, with no inclusions at all under magnification, a gemologist’s first thought is simple:

The “Glass-Filled” Ruby Scam: The Biggest Rip-Off in the Gem World, How to Spot a Worthless Ruby That Will Shatter.

Glass-filled rubies look like a bargain: big, bright red gems for a fraction of the price of “real” ruby. The catch? They’re not just treated—they’re rebuilt. These stones are fragile composites of low-grade ruby and lead glass. They can cloud, crack, or shatter in normal jewelry work. The worst part is many are sold without

Hydrothermal vs. Flux-Grown: Not All Synthetic Emeralds Are Equal, How to Identify the Two Types of Lab-Grown Fakes.

Not all lab-grown emeralds are the same. Two main methods—hydrothermal and flux—produce crystals that look similar to the eye but carry different “fingerprints” under magnification. If you know what to look for, you can tell them apart with a loupe, a microscope, and a few simple tools. This matters because each method affects price, durability,

The Colombian vs. Zambian Lie: Some Jewelers Are Selling High-End Lab Emeralds as “Colombian,” Don’t Get Scammed.

Emeralds are one of the easiest gems to misrepresent. The word “Colombian” adds a premium. The word “lab-grown” erases it. Some sellers exploit that gap by selling high-end lab emeralds as “Colombian.” Others play a different game, calling a stone “Colombian color” while hinting at origin they can’t prove. Here’s how to avoid the trap,

“Oiled” vs. “Resin-Filled”: A Guide to Natural Emerald Treatments, And How to Tell Them Apart from a Worthless Lab-Grown Stone.

Emeralds almost always have fractures and inclusions. That is part of their beauty. It is also why most natural emeralds are “clarity enhanced” before they reach the market. Two common methods are oiling and resin filling. Both make fissures less visible and the color look more even. They also change price, durability, and how you

Natural emeralds and lab-grown emeralds can look nearly identical at a glance.

A clean 10x loupe, steady light, and a few minutes of patient viewing are enough. This guide explains what

The Emerald “Inclusion” Test: Why a “Flawless” Emerald Is Almost Always a Fake, Natural Emeralds Must Have Inclusions (Jardin).

Emeralds are famous for their rich green color—and their “gardens.” Those internal features, called jardin (French for “garden”), are part of how you know an emerald is natural. A perfectly clean, flawless emerald is almost always synthetic or an imitation. This isn’t snobbery; it’s geology. Knowing why natural emeralds have inclusions, what they look like,
