This Coyamito Agate halve is a fascinating study in vertical mineral growth, revealed through a high-visibility big window. The specimen features ethereal soft banding that surrounds a solid quartz-filled core. The primary highlight is the presence of internal tubes and stalactites—slender, finger-like columns that grew into the cavity before being engulfed by subsequent silica layers. Adding to its complexity, the interior is peppered with dotted inclusions, which appear as fine mineral specks suspended within the translucent chalcedony. With only minor fractures, the professional flat mirror polish provides a crystal-clear view of these three-dimensional growth structures.
