This necklace is combination of black bead cubic zircon and white bead pearl. White pearls are the symbol of elegance and beauty and peace. The pearl is often called the "queen of the sea”. The pearl is the oldest known gem, and for many centuries it was considered the most valuable. The pearl is an astral stone for the signs Gemini and Cancer, and astrologers link it to the moon. It was said in some early cultures that the pearl was born when a single drop of rain fell from the heavens and became the heart of the oyster.
