• Full view of the piece in full sun, covered in slightly glittery brick-red druzy. It is flat and irregularly shaped with a hole through the right end.
  • Detail of the brick-red druzy, showing it is semi-translucent with red hematite inclusions. The druzy is composed of well-formed small intersecting pyramid-shaped crystals.
  • View of the piece in indirect light, showing more glitter and a less saturated brown-red coloration. There are several holes in the surface lined with crystals.
  • A side view of the piece, showing it is thin and flat, with a layered appearance of an iron-oxide matrix. It has cave-like holes in the side.
  • View of the other side of the piece, showing layered red rack matrix and a split layer filled with crystals.
  • The back of the piece, partially covered with druzy with an irregular matrix on top. The matrix has oxidized into tones of brown and yellow, looking similar to lichen.
  • Full sun view of the back, showing deeper saturated color to the red druzy. The rough matrix has nice tones of yellow, orange, and red.
  • Detail of an end of the piece showing split layers, with rough matrix on top but glittery red druzy inside.
  • Detail of the druzy on the back, near the hole through the piece. It has excellent triangular form and intersecting growth.
  • Full sun detail view of the druzy, showing deeper red color. There are some clumps of opaque red mineral on top of the druzy.
  • Angled view of the front of the piece, showing the druzy texture with some rhombohedral patterning, and a few clumps of dull opaque red mineral on top.
  • Detail view of the side, showing the iron oxide matrix visible on the side and crust of druzy.
  • Detail view of the holes in the front of the specimen, lined with crystals like little caves.
  • Detail of the hole through the piece, small and oval shape and surrounded by well-form druzy.
  • The mineral on a measuring mat, showing it is about five by two and a half inches, three inches at the widest.

This calcite specimen from Santa Eulalia is a lovely deep red color from hematite (iron oxide) inclusions. An irregular-shaped piece of matrix is covered in glittering red calcite druzy on both sides, and in cracks on the sides. 

Studied closely, this piece has well-formed crystals with beautiful geometry. The druzy is in fact composed of small intersecting pyramid-shaped calcite crystals with beveled edges. There are also calcite rhombohedrons and tabular crystals in the mix, but the bulk of the growth is triangular.

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

** Staining warning! The soft oxidized matrix exposed on the sides will leave red-brown dusty staining on surfaces.
