It's that Gemini time of year from May 21st to June 21st. We are all effected by the alignment of the planets and stars so you may find yourself taking on Gemini traits during this period. In early times people owned crystals and stones for each of the zodiac signs for this very reason. Today many of us only have one stone which is representative of our own sign. Their reason for having all of these crystals in the past was to keep them balanced and whole, working at their very best.
