Massive Biotite Mica specimens, collected from Arendal, Norway. These specimens depict a “massive” crystal structure, as opposed to the more commonly seen sheets. Like all biotite mica, these specimens are dark in colour, exhibiting a dark grey to black hue. Mica is one of the most common mineral groups, with biotite being the most abundant member. Biotite is very common in igneous and metamorphic rocks, with the dark minerals in granites, pegmatites and gneiss often being due in some part to the presence of this black mica. This massive biotite are available in limited supply so we recommend you move fast if you wish to add a piece to your collection. Supplied in a white card tray with information label.

This specific jewelry loupe provides 10x magnification along with a spacious 20mm viewing field, helping reduce eye strain. It also allows users to examine a wide area at once. This Ruper model delivers exceptional clarity in vision thanks to its doublet design with aplantic optics. This means it utilises a combination of concave and convex optical glass to minimize the effects of spherical aberrations.
It’s worth emphasising that Ruper lenses are indeed doublets, despite common misconceptions and sellers’ claims of them being triplets. Their crafting process uses exclusively two optical lenses and a spacer. The lens comes in a stainless steel body with a chrome finish, displaying the ‘Ruper’ name on one side. Another premium magnifier and loupe from this esteemed Japanese brand, it proves invaluable for professionals and enthusiasts in fields like geology, crystallography, and sedimentology for enhanced viewing of rocks, minerals, fossils, and crystals. Additionally, it aids in botanical observations, entomological studies for detailed insect examination, as well as jewelry-making, faceting, and gemstone scrutiny, among other applications where magnification is essential. It comes with a faux leather case. Made in Japan.
Introducing an affordable and versatile hand lens perfect for students, children, and general use.
