Friendship, love and loyalty are represented by this historic celtic design. A Emerald claddagh ring with your birthstone or favorite color makes it even more significant. The birthstone of May, an emerald ring symbolizes the eternally returning spring. The velvety green color of emerald is a perfect match for spring and summer fashions. Once considered more valuable than diamonds, a peridot ring is a must have. This "gem of the sun" is the birthstone of August and is a beautiful match for the lush green tapestry of late summer.
