More on my obsession with the galaxy and the wonder of color in stones. Altho i did purchase these online from India and communication was difficult so I am not absolutely sure if these are not dyed or heated but they are stones and I really love the way this ring wears and feels. The sweet pink planet and the baby blue crescent moon exude innocence to me. The shank on this is a split 20 g band that I sawed and fabricated myself. The range on this is Size 7.5 - Size 9 Great if you have a gift to give someone with an unknown ring size.
