Hello, I found this piece inside an oyster. Is it possible to know the type and value?

It appears to be a blister pearl. The pearl has grown attached to the shell. Blisters are not considered very valuable. Whole pearls, detached from the shell, are valuable.

Yes, that is a blister pearl...but it seems nacreous, as if formed inside a pearl oyster.
What kind of oyster did you find it in? What location?

This photo seems a bit out of focus, but seems a lustrous and pretty blister pearl with a fun story! Perhaps the edge could be smoothed a little and a hole drilled to make into a pendant?

The blister is a cluster of smaller pearls in a very attractive and symmetrical pattern. It would justify a more involved setting such as this Pinctada Maculata shell with comparatively ugly blister. (My wife wears the polished back side forward.)
