Very pretty. I am almost certain the diamond is in the center. The silvery round things around the edge of the circle are silver, but it is hard to distinguish them from what I think is the diamond. The color of the stones on mine are only slightly lighter than the ones shown in the picture, and are all the same color. I like that the bumps at the tips of the amethysts come up slightly higher than the stones. I am guessing this can help prevent another object from knocking off the stones. I wouldn't pay $60 for it, but at $22 I am very happy with this gift for my sister-in-law. My only concern is if the color of the gold changes like one of the reviews mentioned.
Update: This necklace is still intact!
