You and your best friend, you and your beau, you and your baby, your kid, your pet. Represent someone or something you love. In 10k, 14k gold or sterling silver. Wear them both or give the other to your person. Have it engraved or keep it smooth:) 
 
I recommend my Classic Box Chain for Charms as a perfect way to wear it - a nice chain where you can add other charms and wear it everyday:)  
 
Makes a beautiful gift for yourself or someone you love.
