Mine is about 3.6 inches in diameter. I scry with crystal balls that have rainbow inclusions, clear sections, misty sections and internal planes. They do not bother me at all. In fact for me they help. They help me concentrate and not focus on reflections that I see in a clear obsidian piece. Some people need that clarity, like an empty filmstrip, so the scrying can take place. But I find I do better with a little action going on or I find myself focusing on the reflections of the light above or around me, or images of my furniture or the person I am scrying for. However, I don't like super busy pieces either. I can't scry with a rose quartz sphere, for example, or orange calcite. But a semi transparent amethyst, pale citrine, or even a selenite sphere can be amazing!
