Mineralogically interesting small cabinet specimen featuring black, lustrous zirconolite crystals of the historic variety polymignite in a contrasting pegmatite matrix. The specimen comes from H\u00e5kestad Quarry near Tj\u00f8lling, Larvik, Norway, and displays the rare mineralization on several sides. <\/p>\n

Zirconolite var. Polymignite from H\u00e5kestad Quarry, Norway<\/h3>\n

This mineralogically interesting small cabinet specimen displays several black to blackish-brown zirconolite crystals of the historic variety polymignite within a coarse-grained pegmatite matrix. The partly elongated, tabular to prismatic crystal sections are visible on several sides of the specimen and stand out clearly from the lighter matrix minerals because of their strong luster. <\/p>\n

Particularly striking are the black crystals embedded in pink feldspar, together with additional crystal sections in the gray to whitish matrix. Their varied positions make it possible to observe the crystal habit, color, and luster of the zirconolite from several angles. <\/p>\n

Rare Mineral Specimen from H\u00e5kestad Quarry<\/h3>\n

H\u00e5kestad Quarry near Tj\u00f8lling in the Larvik area is known for complex pegmatite mineralization and for a range of uncommon oxide minerals. This specimen is therefore especially interesting as a reference and documentation piece for collectors of rare minerals, Norwegian pegmatites, and systematic mineral collections. <\/p>\n

The specimen measures 6.0 \u00d7 5.0 \u00d7 4.0 cm and weighs 109.3 g. In addition to the black zirconolite crystals, the matrix shows gray, white, and pink feldspar zones that create a varied contrast of color and texture.<\/p>\n

A characteristic and collectible specimen of a zirconolite variety that is only rarely encountered on the mineral market.<\/p>\n
