Now---if you intend on becoming a collector, you are in the right place. The more you look, the more mesmerizing these little orbs become.
If you have been overcome by the beauty and decide to keep a few, post three or four at a time for a positive ID.

This place, “The Marble Connection” has been around longer than you can imagine, the very first marble chat board on the web and still going very strong.
Marble—On!!
