I ordered this and the matching earrings at the same time without ever having seen them in "real life." I was hoping that they would be pretty. I was not disappointed. As soon as I opened the box, I said, "Ooooooh!"
The pendant shines mostly purple and blue colors and it really picks up the light and has long facets along all the edges. The crystal is 3/4 inch square. In case you were wondering, the crystals on the earrings are 9/16 of an inch square. So this is bigger and the frame is wider (about 3/16" versus 2/16" for the earrings.)

As you can see from the photo, the bale is round. It is a 1/2 inch round ring, but it doesn't leave a lot of room at the top for a big chain (as the ring must sit in the corner of the crystal.) I have mine on a thin chain because I thought it set off the pendant better anyway (you have to supply your own chain.)

Just like the earrings, the back of the crystal is plain silver, sort of like a mirror. I don't know what this material is on the back (sterling foil? silver leaf? paint?) but it must serve to reflect the light back through the crystal facets. I am storing mine in the box it came in to prevent any scratching of this backing (even though I am not sure it will indeed scratch, I don't want to take a chance.)

Overall, the pendant and earrings are very different and sparkly. I receive many compliments and questions ("Where did you get those?!?) every time I wear them.
