What is this focal point?

I know I haven't been blogging much this past week. It's been crazy busy at work and by the time I get home, I'm too pooped to go online.

Hey, once I crawl into my massaging recliner with a cat or two in my lap, it's all over. Before I know what's happening, I end up dozing off.

Anyway, this is Friday night so I'm making the time to post because I have a question for you, gentle beader readers:

I did some much-needed gleaning of ye olde beading area and came across this pretty focal point. I gathered up some fire polished Czech glass beads in complimentary tones, added a few dyed freshwater pearls, glass pearls and a goldplated chain and put together a necklace.

Trouble is, I need to be able to list the components and I have no clue what that focal point is. The receipt for purchase is long gone. It's not plastic, it's some kind of gemstone.

Anyone got any clue what it might be? Click on the picture to enlarge it for a better view.
