rutilated quartz

Rutilated Quartz

Here is an old favorite back at the Rock Shed in the crushed rock division.  While I buy this material as Rutilated Quartz, it's really "mixed quartz". It ranges from plain white to smokey quartz with golden rutiles in it. So, if you are looking for high quality Rutilated Quartz, this may disappoint. If however, you want to tumble some mixed colors of quartz with a chance of getting some nice golden rutiles, this is it. From Brazil, this material ranges in size from 1/2" to 1 1/4" but the majority is quite uniform in size around 1 1/4".

Chrysocolla

This is beautiful Chrysocolla from Peru. This will be challenging rock to tumble because of it's hardness of 3 to 3.5. If you are up for the challenge, it will likely take special techniques using corn cob for polishing or 2mm ceramic ball media as explained in our soft stone polishing instructions link below. This material would also polish beautifully into cabochons or free forms on a grinder lap. These would also make beautiful collection pieces for any rock collector.
