I'm pretty happy with these earrings. I've had them for about a month now and really love the color of the stones that I received. They had more veining than is in the picture, but a great color. I'm sure it's just luck of the draw.
The earrings themselves are oval and about the size of a dime.  For me, this is much bigger than I would normally wear, so these are 'special occasion' earrings. But they are definitely not too large and too simple of a design to be garish, imo. They go fantastic with a grey dress and turquoise bracelet that I already have.
The only complaint I have is that the post seems much thicker than my normal earrings and can be tough (painful) to put in. They are not screw backs (which are also tight for me), just smooth, simple hooks.
