Canyonite Sky Laboratory Point System
| Attribute | Description | Scoring Range |
|---|---|---|
| Mineral Inclusions | Density, definition, and quality of copper-silicate inclusions (Papagoite, Ajoite, Shattuckite, Chrysocolla, etc.) | 0–10 points |
| Color in Inclusions | Hue strength, saturation, and contrast of blue, teal, or sky tones within inclusion zones under full-spectrum light. | 0–10 points |
| Translucency | Degree of light transmission and internal illumination through the chalcedony matrix. | 0–10 points |
Scoring and Grade Assignment
| Grade | Total Points | Quality Classification | Description |
|---|---|---|---|
| CS5 | 27–30 | Museum Grade | Exceptional inclusions, vivid celestial coloration, and luminous translucency. Near-perfect matrix harmony. |
| CS4 | 23–26 | Collector Grade | Strong inclusions, vibrant color saturation, balanced translucency, and excellent structural coherence. |
| CS3 | 18–22 | Gem Grade | Visible inclusions, moderate color intensity, sub-translucent glow; minor irregularities accepted. |
| CS2 | 13–17 | Holistic Grade | Soft inclusions, muted sky coloration, limited translucency; grounding and stable. |
| CS1 | 0–12 | Foundational Grade | Minimal inclusions or color; fully opaque; raw elemental matrix suitable for study or lapidary work. |

Canyonite mineral inclusions are confirmed through Raman and XRD analyses to verify mineral identity and structural phases wherever inclusion analysis is possible.
