This is the latest design by Evon. This is a Sterling Silver Harp, that is an Irish symbol of protection. It can be purchased in a variety of stone options. In its original form it comes set with just a single CZ at the bottom as shown in the first picture. For option number 2 you can have it set with a Birthstone in place of the CZ, as seen in picture 2. 
 
Pendant is 1" by 1" and comes on an 18" chain unless otherwise specified.
