Necklaces have a lot to do with how we interact with ourselves and how we act with the external world.  It all depends on how we show it off.  Shorter necklaces that land right around our neck like a choker or on our decollete portray the way we act with the external world.  We are seeking the answers for change from an outside source.  Longer necklaces are less about change and more about an acknowledgment and affirmation of what is already being perceived.  Gemstones, either as beads or pendants, are most effective when they touch the skin on the body.  They interact with the body's energetics, changes in our body temperature, our skin color, and the light that we emit along with the light the stones emit.  And through time, through wearing the pieces, energetic shifts can be witnessed throughout the body as these stones interact with us.  I like to clean the stones before making jewelry out of them with running cold water.  I only like to use gemstones that are as true to it's natural composition as possible; no coloring added.  These are the Earth's treasures...
