"The Claddagh's distinctive design features two hands clasping a heart, and usually surmounted by a crown. The elements of this symbol are often said to correspond to the qualities of love (the heart), friendship (the hands), and loyalty (the crown).
The way that a Claddagh ring is worn on the hand is usually intended to convey the wearer's romantic availability, or lack thereof.
1) Traditionally, if the claddagh ring is on the right hand with the heart facing outward and away from the body, this indicates that the person wearing the ring is not in any serious relationship, and may in fact be single and looking for a relationship: "their heart is open."
2) When worn on the right hand but with the heart facing inward toward the body, this indicates the person wearing the ring is in a relationship, or that "someone has captured their heart".
3) A Claddagh ring worn on the left hand ring finger facing outward away from the body generally indicates that the wearer is engaged.
4) When the ring is on the left hand ring finger and facing inward toward the body, it generally means that the person wearing the ring is married."

We know you've been searching for the perfect ring to give your loved ones, if only spell check could figure out what you're trying to say! Claddagh isn't the easiest phonetically spelled word. Most commonly people leave letters out, like cladagh, claddah, or cladah, or add extras like claddaugh, clauddagh or cladaugh. Some get really creative by searching for clatter, cladder, clauda or claudia rings. However you decide to spell it, the claddagh ring can express your love for another, for your heritage, or for its traditional meaning.
Claddagh comes from the Irish phrase, "An Cladch" which means "flat stony shore." It was the name of the village on the coast of Ireland where the claddagh design originated. The 'gh' ending is added for phonetic English speakers to create the guttural, phlegmy sound that doesn't have a character in our language.
