and the second row, a turquoise, a sapphire and a diamond; and the third row, a jacinth, an agate, and an amethyst; and the fourth row, a beryl, an onyx, and a jasper.

Besides our innate attraction to sparkling objects there are other components as well. We have social and esteem needs and jewelry acts as a sign of a person's wealth and status. Jewelry also acts as a representation of our personality and we identify with it on a deep level. One of the most obvious examples of how jewelry touches our hearts is that wedding and engagement rings symbolize eternal love. Exchanging rings at a wedding ceremony is an unforgettable moment shared by two people in love. This is a tradition followed by millions and millions of people around the world for many years. 

Since it is no secret that humans are attracted to sparkling things, scientists have been trying to figure out out the psychology behind the lure of shimmering objects. This question has lead scientists to conduct research as to what exactly is the reason for this. Interestingly enough, the findings indicate that our preference for shiny things is linked to our primitive need for water as a vital resource. They believe that people’s preference for sparkling objects has deep evolutionary roots and that we are attracted to things that serve a purpose for fulfilling our innate needs.
