A slender clear Quartz point rises above a compact cluster of shorter intergrown crystals. The transparent upper crystal contrasts with the softer white texture of the base, with smaller points gathered around its sides.
The internal detail contributes a second aspect to the specimen’s appearance. Reflections emphasise the outside faces, while light passing into translucent or clearer areas reveals features within the crystal. These are different effects, and appreciating both helps explain why the piece can have visual depth even where its overall outline is relatively simple.
Quartz is silicon dioxide, a mineral whose familiar pointed crystals develop as material is added to growing faces. It occurs in many geological settings, including mineral veins and granite-related deposits. The variety of crystal lengths, orientations and degrees of transparency makes it an especially rewarding mineral to compare: pieces with the same composition can have very different natural architecture.
The glassy lustre of Quartz comes from light reflecting off its surfaces. Clear areas allow a view into the crystal, while internal fractures, veils and inclusions can scatter that light and create softer white regions. These features are distinct from the outer crystal faces. Studying both the interior and the outline adds another layer of interest beyond the familiar pointed shape.
The recorded origin is Jinkouhe District, Leshan, Sichuan Province, China. Within a collection of Quartz specimens, this locality gives the piece a geographical identity alongside its particular crystal habit and natural setting.
The specimen measures 48 × 30 × 25 mm. The proportions give a useful guide to its place in a display, with the individual crystal arrangement and mineral association remaining the principal points of interest.
For display, support the stable base or the supplied mount rather than a projecting crystal. Quartz is relatively hard, but pointed ends and natural contact areas can still be damaged by an impact. Gentle handling helps preserve the arrangement that gives this individual specimen its character.
