This is absolutely my favorite ring! The Moonstone has great fire and is obviously really nice quality. Also, the weight of the piece is nice; not at all cheap!
I ordered the ring in moonstone and am very happy with it. The cabochon is flattened on top which gives the gem a beautiful glow. Mine is lovely shades of blue with hints of purple. The setting sits a bit higher on the hand than I am used to (about 5/16ths) but it doesn't feel awkward or "top heavy". Perhaps this higher placement also helps give the stone so much fire. As to sizing, I wear an 8 and mine is a bit loose but not enough to go down a whole size. I highly recommend this ring!
