Pink sapphires shine brightly as a part of your necklace, arm bracelet or other jewelry. If you received a pink sapphire as a gift or aren't sure whether or not the gem has been altered, you may be curious whether it was naturally or artificially made. Look at the feel, clarity and cut of the gem to determine whether it's natural or not.

Pick the pink sapphire up by hand and gently rub it together with two fingers. An artificial sapphire may feel waxy to the touch, due to a finishing coat of wax some jewelers put on gems, while a natural one will feel smooth and glassy.
Put the sapphire down gently on a flat surface, such as a table. Pick it back up with jeweler's tongs. Turn on a bright light.
Hold the sapphire up to the light and look for blemishes and marks anywhere on the surface or inside the gem, not including the cut lines. All natural sapphires will have some marks, while certain synthetic models will have all blemishes removed before they are sold to consumers.
Examine the cut lines of the sapphire. A natural gem will typically have uneven cuts, while a synthetic model will have cuts that are precise and even, because a jeweler took the time to make them before selling the gem.
Wipe the sapphire off carefully with a cloth before storing it.
