These are onyx earrings. They are in the shape of small hexagonal tubes. The length is 1.3 centimeters. These onyx stones are natural, so the size, shape, and angle of the cut on the edges differ slightly between the left and right earrings. (This is usually not noticeable, but please refrain from purchasing if you are concerned.) They are six-sided, and the way they sometimes glint in the light is lovely. The area circled in blue in the photo appears to have a slight cut. Please purchase if you are not concerned about this. It is not noticeable from a distance. Onyx is also said to protect the wearer. Please refrain from purchasing if you are particular about the details, as these are cut from natural stones.
