The specimen's clean crystal geometry and unusual mineral association make it a highly desirable piece for both collectors and enthusiasts of fine pegmatite minerals.\u003c\/p\u003e\n\u003cp data-start=\"832\" data-end=\"1193\"\u003eThe dominant feature is the impressive Black Tourmaline crystal, displaying sharp terminations at both ends—a growth habit that is significantly less common than single-terminated examples. Its lustrous jet-black surfaces reveal the characteristic striations of Schorl, while the crystal's broad faces and balanced proportions create a bold and elegant display.\u003c\/p\u003e\n\u003cp data-start=\"1195\" data-end=\"1627\"\u003eAdding contrast to the dark tourmaline are small colourless Goshenite crystals, the purest variety of beryl. Their transparent appearance provides a delicate counterpoint to the robust tourmaline crystal. Scattered around the specimen is also Hyalite Opal, a rare form of opal that exhibits a vivid green fluorescence under ultraviolet light, adding an extra dimension of interest for collectors who appreciate fluorescent minerals.\u003c\/p\u003e\n\u003cp data-start=\"1629\" data-end=\"1837\"\u003eThe combination of a large double-terminated Schorl crystal, Goshenite, and fluorescent Hyalite Opal from the mineral-rich pegmatites of Erongo makes this an uncommon and visually striking collector specimen.\u003c\/p\u003e\n\u003ch2 data-section-id=\"l233u5\" data-start=\"1839\" data-end=\"1858\"\u003eSpecimen Details\u003c\/h2\u003e\n\u003cp data-start=\"1860\" data-end=\"1908\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"1862\" data-end=\"1882\"\u003eMineral Species:\u003c\/strong\u003e Black Tourmaline (Schorl)\u003c\/p\u003e\n\u003cp data-start=\"1910\" data-end=\"1969\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"1912\" data-end=\"1936\"\u003eAssociated Minerals:\u003c\/strong\u003e Goshenite (Beryl) \u0026amp; Hyalite Opal\u003c\/p\u003e\n\u003cp data-start=\"1971\" data-end=\"2009\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"1973\" data-end=\"1986\"\u003eLocality:\u003c\/strong\u003e Erongo Region, Namibia\u003c\/p\u003e\n\u003cp data-start=\"2011\" data-end=\"2049\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2013\" data-end=\"2031\"\u003eSpecimen Type:\u003c\/strong\u003e Cabinet Miniature\u003c\/p\u003e\n\u003cp data-start=\"2051\" data-end=\"2081\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2053\" data-end=\"2072\"\u003eCrystal System:\u003c\/strong\u003e Trigonal\u003c\/p\u003e\n\u003cp data-start=\"2083\" data-end=\"2122\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2085\" data-end=\"2096\"\u003eColour:\u003c\/strong\u003e Black, Colourless \u0026amp; White\u003c\/p\u003e\n\u003cp data-start=\"2124\" data-end=\"2146\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2126\" data-end=\"2137\"\u003eLustre:\u003c\/strong\u003e Vitreous\u003c\/p\u003e\n\u003cp data-start=\"2148\" data-end=\"2223\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2150\" data-end=\"2167\"\u003eTransparency:\u003c\/strong\u003e Opaque Tourmaline, Transparent Goshenite \u0026amp; Hyalite Opal\u003c\/p\u003e\n\u003cp data-start=\"2225\" data-end=\"2299\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2227\" data-end=\"2247\"\u003eSpecial Feature:\u003c\/strong\u003e Hyalite Opal fluoresces bright green under UV light\u003c\/p\u003e\n\u003cp data-start=\"2301\" data-end=\"2348\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2303\" data-end=\"2312\"\u003eSize:\u003c\/strong\u003e Approximately 43 mm × 36 mm × 34 mm\u003c\/p\u003e\n\u003cp data-start=\"2350\" data-end=\"2369\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2352\" data-end=\"2363\"\u003eWeight:\u003c\/strong\u003e 148 g\u003c\/p\u003e\n\u003cp data-start=\"2371\" data-end=\"2727\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eThis specimen stands out for its uncommon double-terminated crystal habit, excellent crystal definition, and attractive mineral association.
