A concave cavity in basalt matrix hosts a string of beautifully deep blue cavansite sprays. These sprays reach 1.8 cm wide. Accented with a few small calcite rhombs, and on a carpet of tiny, sparkling heulandite crystals. Minor damage to one of the cavansite sprays, but not a significant detraction. A crack running through the matrix has been stabilized. Three years ago Indian mineral wholesalers reported that the cavansite-producing quarries are either worked out, flooded, or otherwise abandoned, and the cavansite/pentagonite supply is now only a trickle of what it was on the past, with no immediate hopes for more production.
