A small terminated colourless aragonite crystal in amongst crystalline pink aragonite (coloured by strontium?). Width of view 3.5mm. Stack of 30 images. Click on the image below for a higher resolution version.
Flat-lying bladed colourless aragonite crystals on green serpentine with minor dark purple stichtite (not in photo). At one time, these were described as magnesite, but analysis showed them to be aragonite. Ex Jo Price Collection....
A spray of aragonite bladed crystals with unusual zig-zag markings on the faces. Ex Jo Price Collection. Width of view 3.5mm. Stack of 30 images. Click on the image below for a higher resolution version.
Ugly looking aragonite crystals that appear to have been partially etched giving them a greyish appearance, and then clear colourless tips have been added to the terminations. From an old locality. Ex Jo Price Collection....
A radiating spray of aragonite needles. Many of these sprays have seeded on an earlier larger aragonite crystal. Ex Jo Price Collection. Height of view 3.5mm. Stack of 30 images. Click on the image below...
A spray of tapered aragonite crystals, with this image showing some of the typical terminations (and a broken crystal – third from the left, demonstrating the fragile nature of such specimens). Ex Jo Price Collection....
