Instead of developing as a simple collection of separate points, the quartz grows in an intricate interlocking arrangement, producing a framework of intersecting crystals. The result can resemble a natural lattice, with individual crystals contributing to a larger three-dimensional structure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis specimen displays that characteristic growth particularly well. Several substantial, milky quartz crystals form the principal structure, while smaller quartz crystals occupy the spaces around and between them. Some of the smaller crystals are noticeably clearer than the larger surrounding crystals, creating subtle changes in transparency and surface texture across the specimen.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003eFoitite-rich mineralisation\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e adds another interesting dimension. Dark grey to brown material occurs in concentrated areas between the quartz crystals, particularly around some of the central and lower portions of the specimen. These darker areas help define the individual quartz crystals and provide a natural contrast against the predominantly pale colour of the specimen.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eViewed from different directions, the specimen reveals remarkably different aspects of its growth. One face emphasises the larger, softly rounded quartz crystals, while other angles expose deeper pockets filled with smaller crystals and darker mineralisation. This changing appearance is an important part of the appeal of Lattice Quartz, as the internal structure becomes increasingly apparent when the specimen is examined from different viewpoints.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe specimen measures \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e84 × 65 × 41 mm\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e and weighs \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e167 grams\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e, giving it a substantial presence while remaining compact enough for a mineral cabinet or display shelf.
