This stibnite specimen captivates as a pure, solid crystal aggregate of impressive aesthetics, as the flawless crystallography of the stibnite takes center stage. The specimen is entirely composed of robust prisms, densely intergrown subparallel and intricately crisscrossed. The crystals exhibit a deep steel-blue iridescence and lead-gray color and spectacularly sharp longitudinal striations on their faces. This striking relief acts like a natural mirror: even the slightest movement in the light causes the specimen to display a vibrant, high-gloss play of brilliant metallic luster. The fact that the sharp-edged end faces are so perfectly preserved at this density underscores the exceptional quality of this piece.
From a collector's perspective, this is a true rarity. While stibnites from China or Romania dominate the market, Hillgrove (New South Wales) is a well-kept secret and rarely found on trade shows. The orogenic gold-antimony deposit there, with its specific hydrothermal conditions, produced this typical, fascinatingly compact, and powerful crystal formation. Since mining in Hillgrove is primarily industrial and underground, highly crystalline aggregates almost never survive the harsh conditions of daily mining – pieces of this quality were usually rescued by miners before being crushed. A representative specimen that showcases the typical characteristics of this sought-after Australian locality in their purest form and enhances any serious collection.
