I always look at the way the stones are set when I buy jewelry. Shared prongs are not as durable as 4-pronged settings. These stones, tiny as they are, are each set with 4 prongs. I thought that they might not have much sparkle. I was wrong. They seem to catch the light and sparkle more than other moissanite earrings I have purchased. I almost always get a comment about them from people, even strangers, when I wear them. I have two holes in my ears and usually wear these in the lower hole and a colorful earring stud in the upper. For the price, these are a buy!
