Review on Greenbrier Light Blue Marbles for Vase Accents and Crafting - Round Glass Floral (2 Bags) by Morgan Gilmore

Depending on the lighting, it can appear almost black and glossy. When you look through them with the light source they are a nice light green, but when the light source is from above (so you can see the reflection) they appear quite specular and almost black. Also, the spheres turned out to be two similar but not identical sizes and two similar but not identical shades of green. Curious.
