Since the implications of wearing a claddagh ring on a particular hand or finger are different, it is important to understand the right way to wear a claddagh ring. If you look at the above image of the claddagh ring, we will refer to the pointed base of the heart as the tip of the heart. Now read the information below to understand the implications of wearing the claddagh ring in a particular way.
(a) Wearing on the right the hand: Like all rings, the claddagh ring can be worn on the left or the right hand. The claddagh ring worn on the right hand, could have the tip of the heart facing the wrist or facing the finger nails. If the claddagh ring is worn on the right hand with the tip of the heart facing the wrist, it would mean that the person wearing the ring already has someone close to their heart. If the claddagh ring is worn on the right hand with the tip of the heart facing the fingers, it would mean that the person wearing the ring is available.
(b) Wearing on the left hand: The claddagh ring is generally worn on the left hand only if, the person wearing the ring is very close to getting married. The tip of the heart is worn facing the risk. There are no other conditions in which the claddagh ring is worn on the left hand. You would normally not wear your claddagh ring on the left hand with the tip of the heart facing the fingers.
(c) Direction of the heart: We have mentioned above that, the tip of the heart is the bottom portion of the heart. Wearing your claddagh ring with the tip facing the wrist is meant to denote that your heart is already taken. This direction could be adopted when the claddagh ring is worn on the left hand or the right hand. Wearing the claddagh ring with the tip of the heart pointing to the finger nails would mean that, your heart is still available. This position is normally never used for the claddagh ring if, it is worn on the left hand.
You will see from the above explanation that the meaning implied by your claddagh ring, would differ with the hand on which it is worn and also the direction in which the tip of the heart points.
