A low mound of milky quartz crystals, well terminated and grown close together, running from larger crystals at the top to smaller ones along the base. The color is a soft white that lightens toward translucent at the crystal tips, and faint growth lines show inside the larger individuals. At the lower right a small patch of dark host rock carrying brassy pyrite breaks the white ground, the only dark note on the piece.
This is vein quartz from the Bulgarian lead-zinc field in the Rhodope Mountains, the same material that hosts the galena and sphalerite from those workings, here crystallized cleanly into an open pocket. Untreated. Quartz is 7 on the Mohs scale, hard and easy to handle, and at 250g and 101mm it is a manageable size for a desk or a shelf.
Natural quartz crystal cluster, Bulgaria, single piece.

About quartz
Quartz is 7 on the Mohs scale with no cleavage. It is hard, but crystal points and edges can chip when knocked.
Cleaning
Rinse it in lukewarm water and brush off any dirt with a soft brush, then let it dry. Skip ultrasonic and steam cleaners: they can crack the crystals.
Wear and storage
Quartz crystals are hard, but their points and edges can chip if knocked. Store the cluster padded and apart from other specimens.
