• Full view of the front of the mineral in indirect lighting. There are three large colorless calcite crystals perched on an angular druzy on dark matrix.
  • Detail of the largest calcite crystal, showing a modified rhombohedral shape with internal cleavage planes visible. The druzy appears almost cubic in shape
  • Full view in indirect light, good icy colorless calcite color to the druzy with slightly yellow-tinted larger crystals. The dark matrix shows through in the gaps of the druzy.
  • Angled view of the piece, showing druzy is thick and calcite crystals perched atop the piece.
  • Side view of the mineral, showing it is a thin flat piece.
  • The back of the piece, a rough porous dark brown surface.
  • Detail of the two larger calcite crystals in full sun with light catching them to highlight their internal features and faces.
  • Closer detail of the two larger calcite crystals with light catching the internal features of the smaller one
  • Full sun view of the two larger calcite crystals and druzy, showing the material is quite glittery
  • Angled view of the front, better showing the third calcite crystal attached at the top.
  • The mineral on a measuring mat, measuring about three and a half by two and half inches.

This calcite specimen from Santa Eulalia has large colorless calcite crystals and druzy on a dark iron-oxide matrix. The calcite formed a chunky druzy of icy colorless intersecting rhombohedral crystals that almost appear cubic in areas. There are three larger modified rhombohedral crystals perched atop. This is a beautiful example of growth forms typical of this region!

UV reactivity Moderate white fluorescence when exposed to 365nm UV light; reaction stronger in larger crystals.

** Brittle warning! This material is brittle and may shed pieces, limit handling.

** Staining warning! The soft matrix on the back will leave dark brown dusty staining on surfaces.
