This is a very rich specimen!! The matrix is mostly dolomite vein with fine grained dendritic silver embedded in it everywhere. As well, there are lots of much courser veinlets of native silver, as well. Interestingly, there are a couple of blobs of colourless quartz, that have fractured differently than the dolomite and have more silver veinlets in them and no dendritic. Very interesting! Sawn one side rough the other.
