🎉HP!🎉Trilobite Silver Ring (sized 8.5)

This is a super cool ring for all you fossil lovers! It's a large trilobite fossil silver ring, sized 8.5 The ring is not marked sterling silver but is non-magnetic so I suspect it is silver. The fossil measures 1.25" in length and .8" which is larger than most I've seen for sale and is mostly strong condition except for one flaw - it has a crack going across it (see photos). Due to the natural design of the trilobite, however, I feel this is hardly noticeable but I wanted potential buyers to be aware of this.
