This Quartz specimen from a kaolin quarry near Kergantic, close to Ploemeur in Brittany, France, shows numerous closely arranged prismatic Quartz crystals on a compact matrix. The crystals are predominantly whitish to milky, with some tips showing translucent areas. <\/p>\n

Measuring 7.7 \u00d7 5.0 \u00d7 3.5 cm and weighing 124.9 g, this is a cabinet specimen. The specimen was self-collected at the locality and comes directly from the kaolin mining area near Kergantic. <\/p>\n

Prismatic Quartz crystals with milky areas<\/h3>\n

The Quartz crystals form a dense, three-dimensional group with numerous crystals of different sizes. Several crystals rise clearly above the specimen and show well-developed prismatic forms with distinct terminations. <\/p>\n

The crystals are predominantly whitish to milky. Some areas, especially toward the crystal tips, are translucent, while other parts appear more strongly clouded by kaolin or kaolin-bearing material. <\/p>\n

Light-colored to slightly cream-yellow areas are visible on some crystal surfaces and between the crystals. These are associated with the kaolinized environment of the locality and give the specimen a distinctive locality character. <\/p>\n

Quartz from the kaolin mining area near Ploemeur<\/h3>\n

The area around Ploemeur in Brittany is known for its kaolin deposits and associated mining. Quartz veins and crystallized Quartz can occur within the kaolinized rocks, locally producing well-developed crystal groups. <\/p>\n

This specimen comes from a kaolin quarry near Kergantic and was collected directly at the site. Of particular interest is the combination of densely arranged Quartz crystals with locally adhering kaolin-bearing material. <\/p>\n

Its direct provenance from the locality gives the specimen additional documentary interest alongside its mineralogical features.<\/p>\n
