The significance of the horseshoe necklace may vary from one culture to the next one, but the most famous connotation for wearing the latter is that because it is a source of good luck. In fact, a horseshoe is sometimes even hung on doorways because some people believe that doing so will let good karma enter their houses. Some also abide by this practice because of their notion that doing so will avert any possible misfortunes from coming into their homes. Others, on the other hand, just wear horseshoe pendants or hang a horseshoe on their front porch to signify that they are aficionados or enthusiasts of the said animal. Therefore, the purpose behind why people wear any piece of jewelry with a horseshoe on it or why people hang up an actual horseshoe in their homes may not always be the same, but it is for this same reason that the latter has become quite an interesting topic of discussion.
