Heres the deal... I'm interested in finding the perfect stone to set in my engagement ring. So I want an Alexandrite, which is among the rarest of all precious stones. There's a "standard" according to books I've been reading (out dated) that the color change from daylight to incandescent light HAS to be green to red. But I see all these pictures of "Brazilian" Alexandrite and they are blue to pink, light purple to reddish purple. So I'm wondering if the "standard" has changed, or if they're just trying to sell a stone that isn't Alexandrite.

i was just wondering, if einstein travelled on a beam of light while at the same time shining a beam of light, the speed of light isn't like doubled, and c+c=c, so what would happen if say i were to travel on a beam of light shining a beam of light in the other direction, would there still be light emitting from the beam being observed by someone else? what would c-c=?
