ECKER9-1 Eckermannite $18 SOLD

Norra Kärr, Gränna, Jönköping, Småland, Sweden (TL)

6.2 cm x 4.4 cm x 2.3 cm

This specimen consists of green-gray fibers of Eckermannite ([Na][Na₂][(Mg,Fe²⁺)₄Al][(OH)₂|Si₈O₂₂]) mined at the type locality. Eckermannite is a clinoamphibole and an inosilicate. Like the Denisovite above, it probably qualifies as another asbestiform mineral, although the fibers in this specimen are tightly compacted.

EDI9-1 Edingtonite $45 SOLD

Ice River Alkaline Complex, Golden Mining Division
British Columbia, Canada

4.1 cm x 5.5 cm x 2 cm; largest crystal = 7 mm

Edingtonite (Ba[Al₂Si₃O₁₀] · 4H₂O) is one of the rarer zeolites, and the Ice River locality is a standard for the species. The Edingtonites are richly sprinkled on colorless calcites.

ELLE9-1 Ellestadite-(Cl) $16 SOLD

Crestmore Quarries, Riverside County, California (TL)

2.6 cm x 2.1 cm x 1.5 cm

Numerous yellow prismatic Ellestadite-(Cl) (Ca₁₀[Cl₂|(SO4)₃|(SiO4)₃]) crystals frozen in blue Calcite (CaCO₃) from the type locality.

ELP9-1 Elpidite and Arfvedsonite $22 SOLD

Khan Bodgo Massif, Central Gobi Desert, Mongolia

5.9 cm x 3.5 cm x 4 cm

This chunk of Mongolia contains large orange-brown crystal sections of Elpidite (Na₂ZrSi₆O₁₅·3H₂O) with greenish, fibrous Arfvedsonite [Na][Na₂][Fe²⁺4Fe³⁺][(OH)₂|Si₈O₂₂]. High-temperature Elpidites like this one are usually enriched with Ca and K, and are formed in superalkaline granitic massifs. The Khan Bodgo Massif is one of only a few such massifs that are known.

EMQ10-1 Emerald in and on Quartz $56 SOLD

Brumado, Bahia, Brazil

4.8 cm x 2.0 cm x 1.5 cm

This clear, colorless Quartz specimen features a thin, 4.3-cm, pale Emerald inclusion (barely visible in both photos, going almost the full length of the crystal) and a 1.3-cm exterior Emerald. It also has an interesting imprint of a 1-cm Magnesite crystal that either stayed behind in the pocket or perhaps dissolved before this specimen was found. The Emerald on the exterior of the Quartz fluoresces RED in LWUV!

EMQ10-2 Emerald and Uvite in and on Quartz $52 SOLD

Brumado, Bahia, Brazil

4.6 cm x 1.2 cm x 1.0 cm

This is a beautifully tortured little piece with a lot of geologic stories to tell. It consists of two water-clear, doubly-terminated and doubly-included Quartz crystals. The crystal on the right has been bent into a curve that nestles the left crystal and entraps a small cluster of Uvites [Ca][(Mg,Fe²⁺)₃][MgAl₅][(OH)₃|F|(BO₃)₃|Si₆O₁₈], visible as an olive-green smear in the lower photo, center. The right-most crystal has inclusions of long, thin, pale Emerald (Be₃(Al,Cr)₂Si₆O₁₈) threads, visible in the top photo as two straight, almost horizontal lines. The left-most Quartz supports six short, and crudely but nevertheless still doubly-terminated Emeralds on its exterior, as well as a cluster of olive-green Uvites. All Quartz terminations and bend points are either milky or covered with many small faces, attesting to the valiant effort this crystal expended to preserve its form. The Emeralds on the exterior of the Quartz fluoresce red in LWUV, though not as brightly as EMQ10-1.

EMQ10-3 Emerald and Uvite (?) in and on Quartz $15 SOLD

Brumado, Bahia, Brazil

4.8 cm x 1.3 cm x 1.3 cm

A nice, water-clear, doubly-terminated, Tessin-type Quartz with a 2-mm external Emerald and sub-millimeter inclusions of something dark - Uvites? They're not large enough for me to be sure, even under my maximum magnification in the photo at right. The Emerald on the exterior of the Quartz fluoresces red in LWUV, though not as brightly as EMQ10-1.

ENAG9-1 Enargite $38 SOLD

El Guanaco Mine, Guanaco, Santa Catalina, Antofagasta Province, Antofagasta Region, Chile

5.5 cm x 4.6 cm x 3.2 cm; largest crystals ~ 2-3 mm

Sharp metallic Enargite (Cu₃AsS₄) crystals in vugs and seams.

ETT9-1 Ettringite $52 SOLD

N'Chwaning Mines, Kalahari manganese fields, South Africa

12 cm x 4.5 cm x 0.9 cm

Canary-yellow Ettringite Ca₆Al₂[(OH)₄|SO₄]₃· 26H₂O crystals to 6 mm are sprinkled on a thin plate of manganese-rich matrix.

EUC6-1 Euclase on Quartz $75 SOLD

Ouro Preto, Minas Gerais, Southeast Region, Brazil (TL)

4.5 cm x 2 cm x 1.8 cm; Euclase crystal = 1.4 cm x 1 cm

I was very surprised to learn that Ouro Preto is the type locality for Euclase, BeAl[OH|SiO₄]. This specimen has a large Euclase crystal embedded in the Quartz matrix. The tip of the crystal is that particular shade of blue that only Euclase seems to acquire, while other portions of the crystal are clear and colorless.
