If you've never seen a rainbow moonstone in person, I can only say that pictures, no matter how detailed, can't possibly capture the flashes of color this stone reveals as it is turned in the light. It is nothing short of magical! The star of this unusual pentacle is formed from tiny Celtic knots known as "triquetras". These triangular knots radiate outward from the moonstone cabochon in the center, giving the pendant an open and ethereal feel. The Moonstone Triquetra Pentacle Pendant measures approximately 1 1/4" tall, including the bail. It is made of sterling silver, and comes with an 18" sterling silver chain.
