It’s actually a two level structure, the controller die is out of view on the lower layer (but we can see some gold contacts deep down that it presumably connects to). The quartz crystal is a rectangular sheet with a slightly textured surface and rounded corners, with a gold electrode covering most of the top and bottom surface. One side of the crystal hangs over a small rib on the edge of the package but doesn’t seem to touch it (maybe this is an end stop to keep it from breaking if dropped?) while the other side is attached to a pair of gold contacts on the ceramic package with a conductive adhesive of some sort, probably silver filled epoxy.
