All I can say from these photos is that it looks more like a WVS than a slag and that it might be an Alley.
As for the photos, I think you are a bit too close to the marble. It looks this way because the material behind the marble, which is farther away, is in focus but the marble and material in front of it is not. I recommend finding a tall glass or something similar that is about 8-10 inches taller than the marble to use as a "stand" for your phone/camera. Just set the phone on top of the "stand" with the lens off to the side and place the marble directly underneath it so it's in the middle of the frame. This way your camera will be steady when you take the photo. You may have to try a few different heights and light positions to get a nice clear photo but once you figure it out you can just keep doing it the same way and you will never have to worry about blurry photos again. ๐
