A really fine, floater crystal with pleasing light blue color and high, glassy lustre! nice!
4JG45 - Datolite - $ 125 SOLD Dal’negorsk, Primorskiy Kray, Russia miniature, 4.5 x 2.9 x 2.5 cm
Beautiful complex crystals with great clarity and superb luster. Datolites are more commonly equidimensional, so these complex tabular crystals are very attractive and unusual. There is some minor edge wear, but it is hardly noticeable in the sharp brightness of these crystals.
D06-98 - Datolite - $ 800 SOLD Caledonia Mine, Ontonogan County, Michigan, USA miniature, 5.0 x 4.6 x 1.7 cm ex. Martin Zinn ex. Wally Mann
A beautiful half-geode with the most consistent red datolite you could ask for. These datolite nodules are quite rare in such quality, and highly prized by collectors who know their ins and outs. This one is a particularly fine piece for the red variety (the color is due to copper), and is from several prominent collections. I recently saw the exhibit of the Seaman Museum's specimens up in Michigan, and this would fit right in, for quality and visual impact, to their case of the best of them. Note it is so reflective a polish tha tyou can see my photographers reflection!
K202 - Datolite - $ 1450 SOLD Wessels Mine, Kalahari Manganese Fields, South Africa miniature, 4.2 x 3.8 x 2.2 cm
A rare pink datolite, fairly large for the material produced, and with as intense color as I have ever sene in sucha specimen. They were very uncommon, from the mid 1980s.
K209 - Datolite - $ 400 SOLD Wessels Mine, Kalahari Manganese Fields, South Africa miniature, 3.3 x 3.0 x 1.8 cm
A beautiful specimen like no other I have seen from here, with a not so subtle lavender hue to it! Wonderful, curving crystals had us fooled it was calcite...
MD-118184 - Datolite - - Archived Isle Royale National Park, Lake Superior, Keweenaw Co., Michigan, USA small cabinet, 8.3 x 6.0 x 3.3 cm.
8.3 x 6.0 x 3.3 cm. An VERY FINE, large, sliced and polished datolite nodule half from Michigan’s Copper Country. This white beauty is porcelaneous and has an unusual pastel-green core with dentritic, red highlights on the edges (caused by copper , I presume). This showy piece is from Isle Royal in Lake Superior, where not too many datolite nodules have been recovered. Ex. Seaman Museum Collection.
MD-119378 - Datolite - - Archived Mesnard Mine (Quincy No. 8 shaft), Quincy Mine, Hancock, Houghton Co., Michigan, USA small cabinet, 7.2 x 6.4 x 2.8 cm.
7.2 x 6.4 x 2.8 cm. A showy and excellent, slabbed and polished red datolite nodule nicely set in matrix from the Mesnard Mine of Michigan. The datolite has a nice porcelaneous look and the red color is the result of copper inclusions. Red datolite nodules from Copper Country are always in demand. Ex. Dean Martalock and Seaman Museum Collections.
MD-119511 - Prehnite, Datolite - - Archived Lane Quarry, Northfield, Franklin Co., Massachusetts, USA small cabinet, 8.0 x 6.0 x 5.3 cm.
8.0 x 6.0 x 5.3 cm. A CLASSIC, OLD-TIME and SHOWY Lanes Quarry specimen of translucent, sea-green, botryoidal prehnite beautifully complimented with glassy, tabular, off-white datolite crystals on matrix. Here is a very fine combo piece from a famous Massachusetts locality that is always in demand. Ex. George Elling Collection.
MD-119663 - Datolite - - Archived Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia miniature, 4.8 x 3.4 x 2.6 cm.
4.8 x 3.4 x 2.6 cm. These datolites are just amazingly gemmy, like a water-clear quartz or calcite - which is NOT typical for the species and makes this mini stand out. (They are colorless in person - the green tint came from the lighting/camera.) Also, datolites tend to be rather clunky specimens with more matrix than datolite, but the crystals are dominant on this one. They measure to 2 cm.
MD-120401 - Datolite - - Archived Centennial Mine, Centennial, Houghton Co., Michigan, USA small cabinet, 6.7 x 4.5 x 1.8 cm.
6.7 x 4.5 x 1.8 cm. showy and excellent, slabbed green and white datolite nodule from the Centennial Mine of Michigan. The datolite has a nice porcelaneous white rim and the green interior color is the result of copper inclusions. The rind has a nice knobby look and the interior growth patterns in the green area reflect the botryoidal character of the outside. Ex. Frank Henderson and Seaman Museum Collections. Mr. Henderson donated his collection to the Seaman in 1978.

The surface is also populated with numerous terminated quartz crystals up to 1 cm.
