Although the ring that hangs this pendant is sterling silver, I wore this pendant for the first time today on a gold chain.  The colors in this pendant include gold, sea foam green, aqua, sky blue, pink and lilac.  It looks quite lovely laying against skin.  Right before I left work for the day, the sun came through the window, shone on the pendant and cast small circular rainbows all over the wall.  I love swirling it around and watching it change colors.  I would wear this on a more expensive gold chain with my brown velvet dress to a formal occasion.

The size - The surface area of this pendant is about the same as a quarter.  The "thickness" (center point to center point) is almost a centimeter.
