135g Haüyn crystal crown on white matrix – 1.7 cm Royal-Blue aggregate & glimmer contrast Crystals on matrix- 135 g

This 135 g piece (6.1 × 4.1 × 3.1 cm) bears a rare crystal crown made of vividly royal blue Haüyn, with its largest aggregate measuring about 1.7 cm, belonging to a size class that even experienced collectors rarely get to see. Haüyn usually forms tiny grains up to a few millimeters at most — making this intense, large-grained royal blue formation all the more extraordinary.

The haüyne sits parallel to the mica on a light matrix with calcite coating. This white calcite base enhances the color impression of the haüyne and makes the blue stand out even more vividly.

The beige shimmer provides a striking, structural counterpoint: fan-shaped, layered, and silky reflective — while the Haüyn appears in rich, globular-aggregated forms. This interplay of three minerals creates depth, movement, and an exciting visual rhythm.

The combination of ultra-rare Haüyn, unusual size, contrasting shimmer, and the calm white matrix makes this piece a truly exceptional collector's item – mineralogically valuable, visually dynamic, and extremely rare in this form.
