I have been looking around at what people have for sale in terms of juliet lenses and have noticed some differences in the fire lenses. Some fire lenses have more of a gold look to them and others look more reddish/orangish. Then I saw a set of ruby ones that looked almost exactly like the fire ones I thought I had i my set. Is it possible I actually have ruby? I was pretty sure my serial number coincided with plasma/fire. Most pictures I saw were ones off ebay, which I know can have some fakes on it. Any thoughts?
