If you're a Gemini fan, this Sterling Silver Round Zodiac/Star Sign Gemini Pendant Necklace will make a stunning addition to your jewellery collection. Gemini is the 3rd astrological sign in the zodiac and is an air sign. People born between May 21 and June 20 have Gemini as their star sign. Geminis are thought to be versatile, intelligent, curious, good communicators and creatures of duality and multiple perspectives. The pendant features the circle of life; we start at the end and end in the beginning and in the centre of the circle is the Gemini glyph; two vertical lines with a horizontal curved line connecting them at the top and bottom, a depiction of the Gemini star sign which features twins.
