About this specimen

Blades of kyanite stack the full height of this Brazilian block, packed edge to edge like the pages of a swollen book. Some are the flat cornflower blue collectors look for; others pale to pewter and silver-grey where quartz and fine mica have crowded in between, and a few catch the light with the pearly sheen kyanite shows along its cleavage. The back is rough and unworked, and the bladed face is plainly the one to display.

Kyanite is Al2SiO5, formed under high pressure in metamorphic rock, and it is known for a hardness that depends on direction: roughly 4.5 to 5 along the length of a blade and 6.5 to 7 across it. A steel point will scratch it one way and skate off the other. That behaviour earned it the old name disthene, two strengths, and it is worth remembering before anyone tries to clean a blade with a hard tool.

Substantial for its footprint at 10.4 × 6.1 × 5.1 cm and 460 g. No stand is supplied. The specimen in these photographs is the one that ships.
