The Chai is one of the more popular Jewish symbols found in Jewish jewelry. In recent years, Chai pendants have become increasingly popular, especially with men. Unfortunately Jews in many parts of the world do not feel comfortable wearing the more recognizable Star of David symbol and have looked to other designs. Since Chai is made up of two Hebrew letters that can be in either print (block letter modern chai) or script (script letter chai) there are many artistic liberties that can be taken with the design of the Chai making it more abstract and less identifiable while still having deep significance. These is a popular abstract chai and hidden chai necklace.
