Is this glass or a mineral? Weirdest beach glass I've seen!

ID on Sea Glass found at Rappahannock River in Virginia.
By no means am I a sea glass expert or even an amateur. But I have seen sea glass, which is why I begin here.
This item was found on a small shore on the Rappahannock River in Virginia. Size: 1 7/8" at longest side, 1/2" thickness Reasons it may be sea glass:
Reasons it may NOT be sea glass:
- It is somewhat translucent, though more so on the edges.
- It is a striking blue color, as glass can be, and I have no idea what rock/stone
- can have such a vibrant natural color here.
- It has a very interesting triangle shape that does not look natural to me, as it
- has an even ½” thickness on the edges.
- The tips of the triangle shape are more yellow/brown-blue than blue, while the middle is a very dark blue (pics are true to color). The item loses its translucency towards the middle, and becomes very opaque.
- The soft parts have small but smooth bumps like stippling. NOT as smooth as frosted sea glass. Nor does it seem to really have a frosted look about it.
- It has some type of sediment/orange rock layer that is very hard and will not chip off. Between the blue item and this orange layer seems to be pyrite. I have never seen glass with rock/sediment
adhered to it…
- There are spots that seem almost like streaks breaking through into the opaque middle part, which I don’t think occurs in glass…
It definitely is translucent when I hold it up to the light, but what is interesting is that the edges are light, almost a light brown to clear, and the blue gets a darker color towards the middle (of course it is thicker in the middle as well which can lend to its darkness).
It almost looks like a clear stone injected with blue pigment since it does not spread in a perfectly gradual way. And there are portions that are very opaque - even light creamy blue more which is more noticeable when wet, as one of the pictures shows.
Here are two pics of the myster mineral or glass when wet.
The darker orange brown you see is NOT part of the item, just sediment or rock that has adhered to it. When wet, this item shows more lighter blue opaque areas, which also makes me think it is NOT glass...
Any clue what this may be?
My husband thought it may be quartz with cobalt pigment, but we don’t know if that happens naturally…
Any ideas would be helpful! ~ sea glass question submitted by B.M. Fiorito, Williamsburg, VA Scroll down to see comments....
