Plumbogummite -Daoping Mine, Guangxi, China
PbAl₃(PO₄)₂(OH)₅·H₂O
The Daoping Mine, located near Gongcheng in Guangxi Province, China, is world-famous for producing some of the finest lead–phosphate minerals ever found — especially pyromorphite, plumbogummite, and mimetite. Discovered in the 1990s, the mine became an instant legend among mineral collectors for its vibrant colors, exceptional crystal quality, and unique pseudomorph formations.
Why it’s rare:
Daoping is a small deposit that was heavily mined for lead, and most of its collectible zones are now completely exhausted. True specimens from the original finds — especially the blue plumbogummite replacing pyromorphite — are no longer being produced.
Why it’s collectible:
These specimens combine aesthetic perfection and scientific interest. The striking sky-blue or turquoise plumbogummite coating over hexagonal pyromorphite crystals creates a one-of-a-kind contrast of color and form that has made Daoping pieces highly sought-after worldwide, ranking among the most beautiful lead phosphates in existence.

Pyromorphite — Daoping Mine, Guangxi, China
Pb₅(PO₄)₃Cl
The Daoping Mine in Guangxi, China, is world-renowned for producing some of the most vivid and perfectly formed green pyromorphite crystals ever discovered. Found during the 1990s, these specimens stunned collectors with their brilliant lime-to-emerald green color, lustrous hexagonal prisms, and beautifully arranged crystal clusters.
Why it’s rare:
The mine is now largely inactive, and the rich phosphate zones that yielded these masterpieces are completely mined out— making genuine Daoping pyromorphite increasingly hard to find.
Why it’s collectible:
Daoping pyromorphite is prized for its gem-like luster, sharp crystal form, and intense natural color, often considered the world standard for the species. Exceptional pieces from early finds are museum-grade and highly valued by collectors worldwide.

Malachite — Yangchun Mine, Guangdong, China
Cu₂(CO₃)(OH)₂
This spectacular malachite from the Yangchun Mine in Guangdong Province, China, showcases the locality’s signature velvety, fibrous crystal formations with brilliant emerald-green chatoyant bands. The radiating, fan-like structures create an elegant sculptural appearance — a hallmark of Yangchun malachite.
Why it’s rare:
Fine malachite of this quality from Yangchun is becoming increasingly scarce as the mine’s production has sharply declined in recent years. Most specimens were collected during a short period of rich finds in the 2000s–2010s.
Why it’s collectible:
Yangchun malachite is prized for its deep, saturated color, silky luster, and unique wave-like growth patterns, making it one of China’s most admired copper carbonates. Exceptional pieces like this one exhibit remarkable aesthetic balance and three-dimensional form — highly desirable among collectors worldwide.
4
Rhodochrosite — Liubao, Guangxi, China
MnCO₃
The Liubao Mine in Guangxi, China, is celebrated for producing exquisite rhodochrosite specimens distinguished by their deep rose to cherry-red color and translucent, lustrous crystal clusters. Unlike the banded rhodochrosite from South America, Liubao material often forms as scalenohedral or rhombohedral crystals with superb clarity and vibrant hue.
Why it’s rare:
High-quality Liubao rhodochrosite was only found in limited pockets, and mining activity in the area has long ceased. True specimens with strong color and transparency are now hard to obtain on the market.
Why it’s collectible:
Liubao rhodochrosite is highly sought after for its gem-like beauty, fine crystal form, and its place as one of China’s most famous manganese carbonates. Exceptional pieces stand among the finest non-Argentinian rhodochrosites, combining rarity, color intensity, and elegant aesthetics.

Lodolite Quartz (Garden / Inclusion Quartz) — Minas Gerais, Brazil
SiO₂
This stunning Garden Quartz, also known as Lodolite or Inclusion Quartz, comes from the famous mineral-rich region of Minas Gerais, Brazil. The crystal’s interior reveals a miniature “landscape” — intricate mineral inclusions resembling moss, forests, or underwater scenes, beautifully preserved within clear quartz. Under light, internal rainbow reflectionsadd a magical brilliance to the piece.
Why it’s rare:
High-clarity garden quartz with vivid, three-dimensional inclusions is uncommon. Most pieces contain clouded quartz or dull inclusions, but top-grade Brazilian specimens like this one display optical transparency and natural color zoningrarely matched elsewhere.
Why it’s collectible:
Each garden quartz is a world within a crystal — a one-of-a-kind natural artwork formed over millions of years. Collectors prize them for their clarity, depth, and the unique scenic compositions that evoke natural landscapes frozen in stone. Fine Brazilian examples like this are especially sought for meditation, display, and gem artistry.

Kundalini Quartz — Madagascar
SiO₂
This striking crystal cluster from Madagascar is known as Kundalini Quartz, a variety of Citrine or Smoky Quartzcharacterized by elongated, naturally stacked terminations that rise in a spiral-like form — resembling the symbolic kundalini energy ascending through the body in yoga philosophy. Many specimens display golden to honey-yellow hues from iron inclusions and natural irradiation.
Why it’s rare:
True Kundalini Quartz comes from a single locality in Madagascar, and only a limited amount has been mined. Unlike heated citrine, these are completely natural, with their color and formation untouched by artificial treatment.
Why it’s collectible:
Collectors value Kundalini Quartz for both its unique vertical growth structure and spiritual symbolism. The natural color gradients and stacked crystal towers make each piece a one-of-a-kind mineral sculpture — equally admired for its beauty, energy, and geological rarity.

Azurite & Conichalcite on Quartz — Tongdan & Lanniping Mines, Dongchuan Copper District, Kunming, Yunnan, China
Azurite: Cu₃(CO₃)₂(OH)₂
Conichalcite: CaCu(AsO₄)(OH)
Quartz: SiO₂
This exceptional specimen from the Dongchuan Copper District of Yunnan, China, displays a rare association of deep-blue azurite crystals intergrown with vivid green conichalcite, all perched on a bed of sparkling quartz crystals. The brilliant color contrast between the electric blue and bright apple-green hues makes it a visually striking and highly desirable piece.
Why it’s rare:
In the Tongdan and Lanniping mining zones, azurite and conichalcite formed under distinct oxidation conditions, so their coexistence on the same matrix is exceptionally uncommon. When both occur together on crystalline quartz, it represents one of the finest paragenetic expressions of the Dongchuan district — few pockets have produced such material.
Why it’s collectible:
This specimen unites three mineral species of contrasting chemistry and color in perfect harmony, illustrating the unique mineralogical diversity of Yunnan’s copper deposits. The Dongchuan mines, now largely inactive, are a classic locality in Chinese mineralogy. Well-balanced specimens like this are prized by collectors for their beauty, rarity, and geological significance.

Spessartine Garnet — Yunxiao, Fujian, China
Mn₃Al₂(SiO₄)₃
This exceptional spessartine garnet from Yunxiao, Fujian Province, China, displays vibrant orange-red crystals with excellent luster and gemmy clarity, beautifully scattered across a contrasting light matrix.
Why it’s rare:
Formed in granite pegmatites under precise geological conditions, Yunxiao’s garnets exhibit remarkable transparency and color saturation. Mining activity in the region has become very limited, making fine specimens increasingly difficult to obtain.
Why it’s collectible:
Yunxiao garnets are recognized among collectors as some of the finest spessartines in Asia, known for their exceptional color, clarity, and brightness. They represent the strength and refinement of China’s modern mineral discoveries, standing proudly among the world’s most beautiful garnet localities.
