A very rarely seen Ferberite specimen from the famous Siglo XX mine in Bolivia. This attractive large thumbnail features one predominant and very sharp, well-formed blocky crystal of jet-black Ferberite with a few accenting blades of Ferberite and minor associated gem Quartz crystals on a small amount of matrix. Very good quality not only for the locality, but the species in general. Hard to photograph and better in person. If you’re a Bolivian collector, you know how difficult it is to obtain any Ferberite specimens from Llallagua, and this little piece should not be overlooked as it is much better quality than a reference specimen, and would make a great addition to any Bolivian suite.
Locality: Siglo XX Mine (Siglo Veinte Mine), Llallagua, Bustillo Province, Potosi Department, Bolivia
Specimen Size: 2.5 x 1.7 x 1.5 cm (thumbnail)

How Long I Store Your Information
Transfers of Personal Information Outside the EU
I may store and process your information through third-party hosting services in the US and other jurisdictions. As a result, I may transfer your personal information to a jurisdiction with different data protection and government surveillance laws than your jurisdiction has. If I am required to transfer information about you outside of the EU, I rely on Privacy Shield as the legal basis for the transfer, as Google Cloud is Privacy Shield certified.
If you reside in certain territories, including the EU, you have a number of rights in relation to your personal information. While some of these rights apply generally, certain rights apply only in certain limited cases. Your rights are as follows:

- Right to Object. You can object to (a) my processing of some of your information based on my legitimate interests and (b) receiving marketing messages from me. In such cases, I will delete your personal information unless I have compelling and legitimate grounds to continue storing and using your information or if it is needed for legal reasons.
- Right to Complain. If you reside in the EU and wish to raise a concern about my use of your information (and without prejudice to any other rights you may have), you have the right to do so with your local data protection authority.
