An interesting specimen from the volcanic region of northern Bohemia.<\/p>\n<h2>Analcime from Jakuby \u2013 White Crystals on Volcanic Matrix<\/h2>\n<p>This analcime specimen comes from Jakuby near D\u011b\u010d\u00edn in northern Bohemia, Czech Republic, a locality known for its zeolite minerals. Its most striking feature is the dense covering of white to cream-colored analcime crystals, which almost completely coats the upper part of the specimen. Individual crystal faces are clearly visible in some areas, while others form more rounded, botryoidal-looking aggregates.<\/p>\n<p>The grayish-green to beige, weathered matrix contains numerous small, dark, elongated mineral grains. Its appearance suggests a volcanic host rock, although its exact petrographic classification has not been determined. The contrast between the fine-grained matrix and the bright analcime crystals makes this specimen particularly interesting.<\/p>\n<p>Measuring 6.9 \u00d7 4 \u00d7 2.6 cm and weighing 66.5 g, this is a compact collector&#8217;s specimen from northern Bohemia.<\/p>\n<table>\n<tbody>\n<tr>\n<th>Feature<\/th>\n<th>Description<\/th>\n<\/tr>\n<tr>\n<td><strong>Mineral<\/strong><\/td>\n<td>Analcime<\/td>\n<\/tr>\n<tr>\n<td><strong>Locality<\/strong><\/td>\n<td>Jakuby near D\u011b\u010d\u00edn, Czech Republic<\/td>\n<\/tr>\n<tr>\n<td><strong>Color<\/strong><\/td>\n<td>White to cream-white<\/td>\n<\/tr>\n<tr>\n<td><strong>Crystal habit<\/strong><\/td>\n<td>Closely intergrown crystals, partly forming rounded aggregates<\/td>\n<\/tr>\n<tr>\n<td><strong>Matrix<\/strong><\/td>\n<td>Presumably volcanic rock with dark, elongated mineral grains<\/td>\n<\/tr>\n<tr>\n<td><strong>Dimensions<\/strong><\/td>\n<td>6.9 \u00d7 4 \u00d7 2.6 cm<\/td>\n<\/tr>\n<tr>\n<td><strong>Weight<br \/>\n<\/strong><\/td>\n<td>66.5 g<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>White to cream-white analcime crystals from Jakuby in the Czech Republic on a grayish-green, weathered rock matrix.
