Dioptase Crystals on matrix - Height: 8 cm - Width: 5.5 cm- 155.6 g

Superb cluster of di Superb cluster of dioptase crystals on ochre skarn/limestone matrix, from the world-renowned Altyn-Tyube locality, Karaganda Region, Kazakhstan — one of the classic and most celebrated occurrences for this species worldwide. The crystals display the characteristic deep emerald-green colour with strong vitreous to adamantine lustre, and well-developed rhombohedral habit. The colour saturation is exceptional, ranging from bright teal-green in direct light to near-black in the shadows, a hallmark of fine Altyn-Tyube material. No restoration. Minor natural contacts on peripheral crystals, consistent with field-collected specimens. Mineral: Dioptase – Cu₆[Si₆O₁₈]·6H₂O Locality: Altyn-Tyube, Karaganda Region, Kazakhstan Dimensions: 8 × 5.5 × 3 cm Weight: 155.6 g Condition: No restoration Splendido aggregato di cristalli di dioptasio su matrice di skarn/calcare ocra, proveniente dalla celebre località di Altyn-Tyube, Regione di Karaganda, Kazakhstan — uno dei giacimenti di riferimento mondiale per questa specie mineralogica. I cristalli presentano il caratteristico colore verde smeraldo intenso con forte lustro vitreo-adamantino e abito romboedriale ben sviluppato. La saturazione cromatica è eccezionale: verde acqua brillante in luce diretta, con profonde ombre quasi nere, tratto distintivo del materiale fine di Altyn-Tyube. Nessun restauro. Lievi contatti naturali sui cristalli periferici, compatibili con un campione da collezione da campo.
