Very sharp rhombohedral Dolomite crystals with a very well defined interpenetration twin, of considerable size, water-clear, lustrous, and with geometric zoning on the edges. Excellent Spanish classic.

DP16AG6: Dolomite

The Daunis collection is a faithful mirror of the minerals that were found in Spain in the 60’s and 70’s. The Asturreta Quarry, specifically the area called "El Pozo," produced in those years the best known Dolomites and Daunis had the ability to get some of them of extraordinary quality. This piece is a good example.

A curious specimen. It is a Dolomite totally covered (but not pseudomorphosised) by a thin chocolate cover of iron oxides. First impressions when you look at the specimen are: nice Siderite! When you look more carefully you will discover that the primary crystals are really white curved Dolomite crystals totally covered by a lustrous, brilliant, colorful coating. Something different!

JFD182AP2: Dolomite (twinned)

The great classics are always great classics! Even though it is not a top piece, more than anything because of the size of the crystal, it is a Dolomite from 'el pozo' in matrix, undamaged, twinned and has that special 'light', that transparency and luster of the best dolomites from Eugui, those of 'el pozo'

JFD228AP9: Dolomite (twinned)

Eugui dolomites are always exciting. I chose this one for its transparency and for that 'clean' appearance that the dolomites from the area of “el pozo” have; thanks to the good disposition of engineer Juan Córdoba. The crystal has a weird growth on one side, but it is a floater and whole everywhere.

Specimen size: 8 × 6.9 × 4.3 cm = 3.15” × 2.72” × 1.69”

SV480EFX: Dolomite (twinned)

Group of very sharp Dolomite crystals, two of them clearly dominant, rhombohedral, with very marked penetration twins, between transparent and translucent, in rock matrix. Worthy of note is a great dark phantom in the main crystal, quite uncommon in such a size in specimens from this locality. A classic for Spanish mineralogy and especially for this species.
