Canyonite Sky LTD
Canyonite 12ct Rare Gemstone
$36.00
A once-in-a-lifetime rarity from Southern Arizona, this cabochon showcases vivid emerald-green Brochantite crystals, sky-blue Chrysocolla and crimson Cuprite suspended in translucent chalcedony. While Brochantite is sometimes found on quartz or other matrix, it is exceptionally rare included in matrix, especially chalcedony, making this gemstone a one of a kind discovery.
Each piece is unique, limited, and destined for jewelers and collectors who seek the rare.

| 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. |
