Carnelian Druzy Agate Egg — Deep Hollow with Defined Quartz Crystal Rim
Carnelian Druzy Agate Egg — Deep Hollow with Defined Quartz Crystal Rim
A more developed example of a carnelian agate geode formation, this egg features a deep central cavity lined with well-formed quartz crystals and a distinct inner growth structure.
Compared to your previous piece, this one shows a more open void and sharper crystal terminations, making the formation process even clearer visually.
The saturated orange tones are caused by iron oxide (Fe³⁺) within the silica, giving that classic carnelian colouring.
🔍 Key Features
📍 Rich orange carnelian chalcedony body
📍 Deep, well-defined open geode cavity
📍 Visible quartz crystal points lining the interior
📍 Strong contrast between outer polish & inner crystal growth
📍 Internal iron spotting / inclusions adding texture
📍 Natural banding showing silica deposition stages
📏 Dimensions
Weight: 66 grams
(Approx size visually: ~6–6.5 cm tall)
🧪 Geological & Scientific Notes
Mineral Family: Quartz (Chalcedony + crystalline quartz)
Chemical Formula: SiO₂
Crystal System: Trigonal
Mohs Hardness: 6.5 – 7
Lustre: Waxy (chalcedony) / Vitreous (crystal interior)
Transparency: Translucent to opaque
Formation breakdown:
Silica-rich fluids deposit microcrystalline layers → chalcedony shell (agate)
A void remains inside the formation
Later-stage silica crystallises into macro quartz crystals lining the cavity
Iron oxidises within the structure → produces orange/red carnelian colour
This piece clearly shows a two-stage growth system: 👉 outer microcrystalline chalcedony
👉 inner crystalline quartz growth
🧼 Care
Avoid knocks (internal points can chip)
Do not soak for long periods (can dull polish over time)
Clean gently with dry or slightly damp cloth
Store separately to prevent scratches
💡 Why This Piece Stands Out
✔ Larger cavity = stronger visual impact
✔ More defined crystal structure inside
✔ Cleaner contrast between layers
✔ Heavier piece → better perceived value
This is the kind of piece that instantly explains geology without needing words, which is exactly what sells.
