磷灰石 - 藍色磷灰石單尖水晶（巴基斯坦）

I wasn't expecting the blue to shift so much depending on the light — almost teal in the sun, deeper in the evening. The point sits flat on its base too, so it stands fine on my windowsill without wobbling.

The terminated tip on mine is a clean sharp point, not chipped like some raw apatite I've seen. Sitting it by a window, the natural blue goes almost teal where the light hits the flat faces. Really happy with it.

The blue on this one is deeper than I expected from the photos, almost teal in sunlight. Mine has a small natural chip near the base but the point itself is flawless, and it sits nicely on my windowsill.
