A free-standing geode section from a small-scale quarry operation in southern Brazil, sourced through a private importer Joseph has worked with since 2008. The interior crystal points are a deep violet with good transparency, and the basalt matrix has been left largely uncut. Stands 22 inches tall and weighs approximately 34 pounds.
A cross-section slab showing the characteristic banded green patterning of malachite from a Central African source, cut and polished on one face and left raw on the reverse. The banding is unusually tight and regular. Measures 14 by 9 inches, mounted on a custom steel stand.
A naturally occurring rosette formation of selenite blades from the Chihuahuan Desert region, collected during Joseph's 2023 sourcing trip. The formation is intact with no repairs or reconstruction. Approximately 8 inches across, with the characteristic warm tan coloring of the region's gypsum deposits.
A freeform-cut piece of labradorite from a Scandinavian source, polished on all faces to show the full labradorescence across the surface. The dominant flash is a deep teal shifting to gold at certain angles. Weighs 6.2 pounds and sits stably on its own base without a stand.
A flat, radial pyrite formation. Sometimes called a pyrite dollar. From a coal-bearing formation in Illinois, a classic American mineral specimen type. This example is 5.5 inches in diameter with sharp, well-defined crystal blades radiating from the center. Comes with a small acrylic display easel.
A 3-inch sphere carved from a single piece of rhodonite, showing the characteristic pink-to-red ground color with black manganese oxide veining. The carving and polishing were done by a lapidary Joseph has worked with in Tucson for over a decade. Comes with a turned wooden ring stand.
A polished limestone plate from Morocco containing multiple orthoceras fossils. Straight-shelled cephalopods from the Devonian period. The plate measures 18 by 12 inches and has been polished to a matte finish that shows the fossil detail without the high gloss that can look artificial. Suitable for wall mounting or display on a low stand.
A cabinet specimen showing black schorl tourmaline crystals growing through a milky quartz matrix, from a pegmatite deposit in the New England region. The contrast between the jet-black tourmaline and the translucent quartz is particularly clean in this example. Measures 5 by 4 inches and sits on a small brass display foot.
The shop is open Tuesday through Sunday. Joseph is usually there and happy to talk through any piece in the collection.
