| This lustrous black prism came to me identified as foitite. Collected circa 1980s. Although foitite and schorl cannot be told apart without analytical methods, I will have to assume that this is foitite since the specimen was part of Dr. David London's Collection, and he is considered a pegmatite expert. |

Each of the specimens in my collection is accompanied by a numbered label identifying the species and location. About a year ago I began the process of attaching a corresponding number to the mineral. In spite of this being a huge undertaking with several thousand specimens to complete, it has been both an interesting and enjoyable project. Some of the specimens have been hidden away for quite a while and it has been fun to reacquaint myself with them. I've also had a chance to think about the people that once owned or collected them, many who are no longer with us. I came across the following two pieces this morning and thought I would share them here.
| Mineral: | Quartz |
| Locality: | | Itinga, Jequitinhonha, Minas Gerais, Brazil | |
|
| Dimensions: | 3.6 x 6.7 cm |
| Description: |
| A transparent quartz crystal with smoky phantoms from the Santa Clara pegmatite. Midway down the crystal there is a fluid-filled cavity with a movable bubble. Obtained from Luiz Menezes in 2004. |
