Bastnäsite's significance in modern technology has made it a strategic mineral, with global demand increasing as industries strive to adopt renewable energy and advanced electronic devices.

Birdseye Marble is the name used by the building–stone / decorative-stone industry for a particular limestone found in Utah that has distinctive fossilized algae ball structures (“birdseyes”) visible in the rock.

Rhyolite is a silica-rich volcanic igneous rock. It is essentially the volcanic equivalent of granite. Because it cools quickly (lava or volcanic flows), rhyolite often crystals too small to see with the unaided eye or even a glassy texture in some cases.

Brockman Jasper is prized for its rich, varied coloration. Typical colors include yellows, reds, olive greens, sometimes blues and blacks.

Brucite is known to have a higher magnesium content than any other industrially-used magnesium-bearing mineral (up to 65%MgO), and this makes it a highly effective agent for wastewater treatment and flue-gas desulphurization.

Bruneau Jasper is a variety of jasper, and more specifically a type of picture jasper. It shows layered / orb (egg-shaped) patterns of earthy tones — commonly browns, reddish browns, creams, and sometimes hints of red, green, or orange.

Despite its name, Bumblebee Jasper is not a true jasper Instead, it is a silicified volcanic material composed mainly of Sulfur Arsenic Manganese oxides and pyrite. The banded yellow-orange-black patterns resemble the coloration of a bumblebee — hence the trade name. It’s only known source is an active volcano.
