• Full view of the front of the piece, a rectangular specimen covered in bumpy botryoidal growths composed of small black, red, and colorless crystals.
  • Detail view of one of the larger yellow-tinted calcite crystals on the surface of the druzy, with a patch of red coloration inside it. The fingers holding the piece are all covered in chocolate-brown powder.
  • Angles view of the front of the piece showing it isn't flat, but one end bends up. The druzy can look flat but glitters in indirect lighting.
  • The piece in full sun, showing darker red-black color and not much glitter.
  • A detail view of the botryoidal pattern on one edge, showing they are composed of an aggregate of intersecting angular matte red, black, and shiny yellowish-colorless crystals.
  • Detail of the mix of red, black, and colorless crystals composing the botryoidal growth. The angled view shows the three-dimensional pattern
  • Side view of the piece showing it is on a flat piece of iron oxide matrix, with a dark red-brown coloration.
  • The back of the piece, a rough surface of dusty red oxidized matrix.
  • Detail view of an end with more black-white druzy pattern and less red crystals in the mix. Two larger angular yellow calcite crystals are on the surface
  • Detail of the red-black crystal aggregate in full sun, with one of the larger calcite crystals in the foreground. It looks as though it has a opaque yellow layer under the surface.
  • Scale image of the piece on a measuring mat, measuring about five inches by two and a half wide.

This is one of my favorites of the Santa Eulalia calcite material. The specimen has formed botryoidal (round, bubbly) shapes composed of a speckled combination of red, black, and light yellow crystals. Under magnification they appear to be intersecting rhombs of calcite, some heavily included with hematite which causes both the black and vivid red colors. The red and black crystals are mostly matte but there is some glitter to the druzy.

Several larger calcite crystals have grown on the surface. They have a yellowish coloration under the surface with some transparency, and are included with the red and black material.

** Staining warning! The soft matrix on the back will leave red-brown dusty staining on surfaces. I really mean it with this piece, look at my hand in the photos!
