Rubies can be the most valuable colored gemstone, based on price-per-carat. However, there are a lot of fakes out there; the safest way is to take the stone from a certified gemologist.
Here are few tricks that may help you to identify genuine Ruby:
According to best astrologer in Delhi, real rubies glow with a deep, vivid, almost “stoplight” red. Fake gems are often dull. Take a magnifying glass. Check for a consistent and even color throughout the stone. Fakes are more likely to contain blemishes and impure spots. Fake gems are often dull. If the gem is very dark red, then it may be garnet instead of a ruby.
Compare the ruby stone to a shard of red glass. Rubies and other varieties of sapphire are often faked as glass. If the glass and stone look similar, then you may just be holding two pieces of red glass.
Try to scratch the surface. Real rubies are extremely hard stones. Grind a fingernail or a coin into the surface of the “ruby” and see if you are able to scratch it. If the ruby shows a scratch, then there’s a good chance that it is not a real ruby. Only a diamond can scratch a ruby.
See if the ruby rubs off on another surface. Gently scratch the stone against a hard, smooth surface: porcelain tile or a piece of clear glass. If you see red mark on the surface, then it might be a sign that the gem is artificially colored.
The stones commonly used as ruby imitations include garnets, tourmaline, glass, and composite gems.
