Like waves on a clear blue sea, or twisting wind-swept clouds, these whimsical designs are an artistic expression of spirit and uniqueness. Yellow gold brings out the bronze and golden colors inside a smoky quartz pendant. White gold will highlight the brown and grey tones of the gem. Either way, you can't go wrong. Emerald is associated with Venus, the Greek goddess of love and beauty. They say an emerald pendant can protect lovers from unfaithfulness.
