Synthetic rubies still give us real ruby rings, because rubies created in laboratories are no less “real” than natural rubies. It is often very difficult to tell natural from synthetic. Gemologists use the consistency of color, shape and clarity that they find in natural rubies to differentiate the gems from their more flawed, synthetic counterparts. Fake rubies, on the other hand, are glass, and they come nowhere near the real thing.
At LenYa, we offer only real ruby rings. Fake rubies tend to be bigger than their natural counterparts and are very red in color. In addition, surface scratches and tiny bubbles often give them away. A fake's facet edges are soft, while true rubies have sharp edges. Rubies can be tested for light absorption and inclusions specific to synthetic stones to determine their authenticity.
Look for patches of uneven lustre when reflecting light off the surface of a ruby. If you find a patchy spot, your gemologist can perform chemical dips and microscopic examinations to determine whether it has been patched or filled with glass. Remember, a ruby is never anything but a ruby; gemstones like those in real ruby rings don't have nicknames. For example, if you encounter an "American ruby", it's a garnet; a "Bohemian ruby" is rose quartz.
