Canyonite Reserve Slabs
A rarity from Southern Arizona, these slabs showcase vivid Papagoite, Shattuckite, Ajoite, Brochantite, Chrysocolla, and Cuprite suspended in a chalcedony matrix. Brochantite commonly forms as surface crystals, it is a rare occurrence to find Brochantite crystals inside the matrix.
Each slab is unique, limited, and destined for lapidary artists and collectors who seek the rare. Slabs displayed wet to show color.
Extensive comparisons against global mineralogical references, including Mindat.org, RRUFF, and other academic collections, reveal no documented parallel material exhibiting this exact mineral assemblage within a chalcedony matrix.
ā¢ One-of-a-kind and permanently finite
ā¢ Single-Deposit Provenance-This material comes from a non-repeatable discovery. Once exhausted, no additional material of this type is expected.

Scoring and Grade Assignment
| Grade | Total Points | Quality Classification | Description |
|---|---|---|---|
| CS5 | 27ā30 | Museum Grade | Exceptional inclusions, vivid celestial coloration, and luminous translucency. Near-perfect matrix harmony. |
| CS4 | 23ā26 | Collector Grade | Strong inclusions, vibrant color saturation, balanced translucency, and excellent structural coherence. |
| CS3 | 18ā22 | Gem Grade | Visible inclusions, moderate color intensity, sub-translucent glow; minor irregularities accepted. |
| CS2 | 13ā17 | Holistic Grade | Soft inclusions, muted sky coloration, limited translucency; grounding and stable. |
| CS1 | 0ā12 | Foundational Grade | Minimal inclusions or color; fully opaque; raw elemental matrix suitable for study or lapidary work. |
