JR57F5: The crystal is doubly terminated and accompanied by other smaller ones. It shows off its slender silhouette.
Aurangabad, Maharashtra  India (±1998)

Specimen size: 5.8 × 3.2 × 2.9 cm = 2.28” × 1.26” × 1.14”

JP57G6: Typical crystallization of Stilbite rising up on a little matrix and with little Stilbite crystals at the base. A graceful piece, of clear color and silky luster.
Jalgaon District, Maharashtra  India (±2002)

Specimen size: 5.6 × 4.3 × 3.5 cm = 2.20” × 1.69” × 1.38”

JC14E7: Good composition: first there is pink Heulandite-Ca, then Stilbite-Ca with large, white crystals, and then finally in the center a large, white Calcite.
As is so often the case with Jan, esthetic and unusual.
Pandulena Hill, Nasik, Maharashtra  India (±2003)

Specimen size: 9 × 6 × 5 cm = 3.54” × 2.36” × 1.97”

Main crystal size: 3.6 × 3.2 cm = 1.42” × 1.26”

JB12N1: Bow-tie growths, some of them doubly terminated that contrast on a bed of small orange crystals of Heulandite-Ca and on a matrix of much altered basaltic rock.
Dharampur, Gujarat  India (±2000)

Specimen size: 9.3 × 7.6 × 3.9 cm = 3.66” × 2.99” × 1.54”

Main crystal size: 3 × 1.5 cm = 1.18” × 0.59”

JR11N1: Clear crystals of Fluorapophyllite-(K) formed by the prism and a very acute dipyramid, with very sharp crystals of Stilbite-Ca and on a columnar growth of Quartz.
Shakur Quarry, Nasik, Maharashtra  India (±2003)

Specimen size: 13 × 3.1 × 3 cm = 5.12” × 1.22” × 1.18”

Main crystal size: 2.3 × 0.9 cm = 0.91” × 0.35”

JT14F5: I find it hard to imagine how something like this formed. The center, possibly of a Quartz stalactite, has been completely covered by Fluorapophyllite-(K) crystals of various sizes. A small brown Stilbite adds to the specimen.
Nashik District (Nasik), Maharashtra  India (±2002)

Specimen size: 14.5 × 6 × 3.5 cm = 5.71” × 2.36” × 1.38”

JD86G6: Undoubtedly the most prominent aspect of the piece is its color. An intense and unusual orange color, affecting both the Fluorapophyllite-(K) and the Stilbite and contrasting with the matrix, dark in some places, white or pink in other. A very attractive ensemble.
Nashik District (Nasik), Maharashtra  India (±2002)

Specimen size: 16 × 14.5 × 6 cm = 6.30” × 5.71” × 2.36”

JA66F2: Most of the crystals of Fluorapophyllite-(K) are doubly terminated, formed from a prism and very sharp pyramids. The brilliance and transparency are very intense and the crystals of pink Stilbite seem to soften the esthetics, giving balance to the specimen.
Jalgaon District, Maharashtra  India (±1996)

Specimen size: 13 × 8 × 4.5 cm = 5.12” × 3.15” × 1.77”

Main crystal size: 2.9 × 1 cm = 1.14” × 0.39”

JE89E5: Yes, this is an exceptional specimen! The inclusions of Julgoldite-Fe that dye the crystals of Fluorapophyllite-(K) towards the bottom of the specimen, by the contrast they create, make the transparent ones in the upper half very appealing. While the photo cannot show it, the play of color and reflections is spectacular.
Jalgaon District, Maharashtra  India (±1988)

Specimen size: 9.8 × 7 × 4.7 cm = 3.86” × 2.76” × 1.85”

JB62J7: Doubly terminated crystals, green and transparent, that combine the faces of a very short prism with the dipyramid and the pinacoid, and, so, they take cubic shape. The matrix is also rich in groups of bow-tie shaped Stilbite.
Lonavala, Maharashtra  India (±2001)

Specimen size: 8.1 × 5.6 × 3.7 cm = 3.19” × 2.20” × 1.46”

Main crystal size: 1.2 × 0.9 cm = 0.47” × 0.35”

JY11N1: Pseudocubic green crystals formed by the prism, a dipyramid and the pinacoid. They are on matrix, with Stilbite-Ca, and partially coated by fibrous crystals of Okenite.
Lonavala, Maharashtra  India (±2001)

Specimen size: 11 × 9 × 3.8 cm = 4.33” × 3.54” × 1.50”

Main crystal size: 1.8 × 1.5 cm = 0.71” × 0.59”

JZ9N1: Pseudocubic green bright crystals of Fluorapophyllite-(K) formed by the prism, a dipyramid and the pinacoid. They are on matrix, with bow-tie growths of Stilbite-Ca and very bright crystals of Heulandite-Ca.
Pashan Hills, Pune District, Maharashtra  India (±2001)

Specimen size: 9.4 × 7.1 × 3.4 cm = 3.70” × 2.80” × 1.34”

Main crystal size: 2.1 × 1.9 cm = 0.83” × 0.75”

JC87E8: An explosion of form and brilliance. For all my experience in color analysis, I cannot quite understand how such gentle colors can result in the superb contrast this specimen has. All the minerals, Fluorapophyllite-(K), Scolecite and Stilbite, seem to combine with great elegance.
The excellent state of the specimen, which looks very fragile and delicate, show how well it has been cared for by those who collected it and have looked after it since.
Rahuri, Maharashtra  India (±2002)

Specimen size: 14.5 × 9.5 × 6 cm = 5.71” × 3.74” × 2.36”

Main crystal size: 2 × 0.9 cm = 0.79” × 0.35”

JB68E7: This one deserves a good description. The crystals of Fluorapophyllite-(K) are very long (prismatic) and seem to fly on the matrix. They are a deep green color. Between them there is something that looks like a coral Aragonite – in reality it is Scolecite. So between these the over effect is pleasing and it would look great in a cabinet display.
Rahuri, Maharashtra  India (±2002)

Specimen size: 11 × 9 × 5.2 cm = 4.33” × 3.54” × 2.05”

Main crystal size: 5.5 × 1.6 cm = 2.17” × 0.63”

JV90E5: Elegance and beauty combine in this sample that Jan Buma got in Jalgaon. Luminous, clean, with crystals that appear to be very well defined, given the contrast between the green and the white.
The specimen has been reviewed, photographed and published in the magazine ‘Mineral Up’ on page 65 in number 2011/1
Jalgaon District, Maharashtra  India (±2000)

Specimen size: 7.2 × 5 × 3.7 cm = 2.83” × 1.97” × 1.46”

Main crystal size: 1.3 × 0.5 cm = 0.51” × 0.20”

JB87E8: Unlike other Cavansites this one has thick tabular crystals that are well separated from each other and are very luminous. They are perfect and well positioned on the Stilbite matrix. Much better than many of the other Cavansites we have seen.
Wagholi Quarry, Wagholi, Pune District (Poonah District), Maharashtra  India (±2001)

Specimen size: 8 × 6.8 × 4 cm = 3.15” × 2.68” × 1.57”

Main crystal size: 1.2 × 0.5 cm = 0.47” × 0.20”

JA8J7: Green globular growths of Prehnite and, on them, there are clear prismatic crystals of Fluorapophyllite-(K), most of them doubly terminated.
Malad, Bombay, Maharashtra  India (±2001)

Specimen size: 6.8 × 4.6 × 3.1 cm = 2.68” × 1.81” × 1.22”

JA76E7: There is good contrast between the yellow Calcite and the green spherical Prehnite. The crystals of calcite are well positioned on the Prehnite matrix and the overall effect is delicate and soothing. A very fine specimen.
Malad quarry, Bombay, Maharashtra  India (±2003)

Specimen size: 11.5 × 7 × 6 cm = 4.53” × 2.76” × 2.36”

Main crystal size: 2 × 1.4 cm = 0.79” × 0.55”

JA96F0: This crystal, a simple scalenohedron, is transparent so one can see something unusual within it: a ‘fuzzball’ of Okenite inclusions! The faces of the crystal are partially covered by green Fluorapophyllite-(K) and white Stilbite. On the rear the areas of exfoliation do not affect the esthetics of the specimen.
Pune District (Poonah District), Maharashtra  India (±2002)

Specimen size: 11.5 × 8.5 × 9.5 cm = 4.53” × 3.35” × 3.74”

JE64G6: Floater, transparent crystal of Calcite with an original covering of clear Stilbite and green Fluorapophyllite-(K). On the back of the Calcite there is a little matrix with Okenite inclusions in Calcite.
Pune District (Poonah District), Maharashtra  India (±2002)

Specimen size: 8.2 × 6.5 × 4.8 cm = 3.23” × 2.56” × 1.89”

JJ88F1: We have often seen in other specimens how Jan's good taste and sensitivity led him to select simple and small examples of the best of each mineral. This is one of the best examples of his style. The radial bundles of Scolecite compete with each other to show off their beauty. The central crystal of Fluorapophyllite-(K), suspended on a bundle of Scolecite as if by magic, is the final touch to this work of art.
Pune District (Poonah District), Maharashtra  India (±2000)

Specimen size: 20 × 11 × 11 cm = 7.87” × 4.33” × 4.33”

JV58F1: Nodules of snow white Gyrolite surrounding the trunk of Prehnite, which is clear. So white on white, but for all that it has intensity and life.
Nashik District (Nasik), Maharashtra  India (±1991)

Specimen size: 6.3 × 3.5 × 3 cm = 2.48” × 1.38” × 1.18”

JV58F2: The rare mineral Julgodite-(Fe) covers the basalt matrix. The small crystals, which are quite dark, are noticeable as they contrast well with the crystals of Fluorapophyllite-(K), which are doubly-terminated, brilliant, water clear and with sharp pyramids.
Jalgaon District, Maharashtra  India (±2000)

Specimen size: 20 × 13 × 5 cm = 7.87” × 5.12” × 1.97”

Main crystal size: 1.4 × 0.5 cm = 0.55” × 0.20”

JB6E8: A well formed sample that is three centimeters tall. The Elbaite crystal is well defined and the crystals of 'lepidolite' give it an elegant touch.
Himalaya Mine, Gem Hill, Mesa Grande District, San Diego County, California  USA (±1979)

Specimen size: 3.2 × 1.9 × 1.7 cm = 1.26” × 0.75” × 0.67”

JH14E5: This one appeals to me because it is unusual. The Calcite crystals, which are very well defined, doubly terminated, and clear, appear to be randomly spread across the dark matrix.
Minerva I Mine, Ozark-Mahoning group, Cave-in-Rock Sub-District, Hardin County, Illinois  USA (±1980)

Specimen size: 8.8 × 6 × 6.5 cm = 3.46” × 2.36” × 2.56”

Main crystal size: 2.9 × 0.9 cm = 1.14” × 0.35”

JD36E3: All the pseudo minerals I have seen seem rather mat to me, and when one is dealing with limonite they tend to have an earthy look. So this one stands out for the surprising brilliance and its achitecture, which is very fine.
Pelican Point, Utah Lake, Utah County, Utah  USA (±1996)

Specimen size: 4.4 × 3.2 × 3.6 cm = 1.73” × 1.26” × 1.42”

Main crystal size: 2.1 × 2 cm = 0.83” × 0.79”

JX63F1: A small, complete specimen that has all the features typical of its bigger brothers. So it is a good example for those people who love miniatures, above all else for its intense color.
Bunker Hill Mine, Bunker Hill properties, Kellogg, Coeur d'Alene District, Shoshone County, Idaho  USA (±1995)

Specimen size: 1.7 × 1.3 × 1.5 cm = 0.67” × 0.51” × 0.59”

Main crystal size: 0.5 × 0.5 cm = 0.20” × 0.20”

JA26E8: For its size the sample is really precious. Like a fossilized crystal of fern, the Silver surrounds the Calcite matrix, both of which sit on a fragment of rock that acts as its matrix.
Batopilas, Andrés del Río District, Municipio Batopilas, Chihuahua  Mexico (±1993)

Specimen size: 3.6 × 2.5 × 2 cm = 1.42” × 0.98” × 0.79”

JA13E5: This elegant specimen appealed to me because of its nice color hints. With thin matrix on which the, sometimes doubly terminated, crystals of amethyst grow.
Piedra Parada (Las Vigas), Municipio Tatatila, Veracruz (Veracruz de Ignacio de la Llave)  Mexico (±1979)

Specimen size: 2.9 × 2.7 × 1.4 cm = 1.14” × 1.06” × 0.55”

Main crystal size: 1.8 × 1.1 cm = 0.71” × 0.43”

ER96E5: Superb group of deep blue Azurite with hints of green where it has been converted into Malachite. The crystal is complete at the base (it is recrystallized) and the upper terminations are perfect, with no dings.
Touissit, Touissit District, Jerada Province, Oriental Region  Morocco (±1982)

Specimen size: 3.7 × 1.8 × 1.1 cm = 1.46” × 0.71” × 0.43”

EH96E3: Small but great. Really good color and presentation of a group of crystals that have no damage to their tips. So almost a miracle!
Bou Azzer mining district, Drâa-Tafilalet Region  Morocco (±1991)

Specimen size: 2.2 × 1.2 × 1.1 cm = 0.87” × 0.47” × 0.43”

Main crystal size: 0.6 cm = 0.24”

JK13E8: Balanced group of crystals of Sulphur on Calcite matrix. As is so often the case with this collection it was carefully selected to provide great pleasure.
Machów Mine, Tarnobrzeg, Subcarpathian Voivodeship  Poland (±1991)

Specimen size: 5.6 × 3.5 × 2.8 cm = 2.20” × 1.38” × 1.10”

Main crystal size: 2.3 × 1.8 cm = 0.91” × 0.71”

ET97E7: This has a very lively and extraordinary color. It is also special as these Barytes rarely appear on the market, and when they do come from old collections (which is the case with this one – it has both Jan Buma and Geologisch Centrum de Ootmarsum, Holland labels.) Very spectacular, given its intense color.
Pöhla, Schwarzenberg District, Erzgebirgskreis, Saxony/Sachsen  Germany

Specimen size: 6 × 3 × 4 cm = 2.36” × 1.18” × 1.57”

Main crystal size: 4.8 × 2.9 cm = 1.89” × 1.14”

JD46E5: Both sides are complete, and also it is soft, delicate, sweet, …. How can one describe this one? You need to hold it!
Alto da Pitorra, Laranjeiras, Galiléia, Vale do Rio Doce, Minas Gerais  Brazil (±1993)

Specimen size: 2.9 × 3.1 × 1.3 cm = 1.14” × 1.22” × 0.51”

Main crystal size: 0.8 × 0.4 cm = 0.31” × 0.16”

JL12E3: Great brilliance and lots of color. I like the shape and I also like the fact that, while it is metallic, it does not look heavy.
Quiruvilca Mine (La Libertad Mine), Quiruvilca District, Santiago de Chuco Province, La Libertad Department  Peru (±1983)

Specimen size: 6.5 × 5.9 × 3.9 cm = 2.56” × 2.32” × 1.54”

Main crystal size: 3.5 × 3.2 cm = 1.38” × 1.26”

JA11E5: Intense in color, this Quartz crystal stands out from the rest of the specimen as it is doubly terminated.
Moralia, Cavendish, Victoria  Australia (±1998)

Specimen size: 3.8 × 3.2 × 3.2 cm = 1.50” × 1.26” × 1.26”

Main crystal size: 3.4 × 2.5 cm = 1.34” × 0.98”
