1. Parallel translucent sulphur crystals, with small remnants ofbitumen.2. Several transparent sulphur crystals, on a bitumen-coatedaragonite matrix.3. Bright yellow sulphur crystals (up to 2.8cm) on a plate ofaragonite microcrystals.4. Bright yellow sulphur crystals on a matrix.5. Groups of parallel transparent sulphur crystals on a matrix.6. Perfect sulphur crystal and other smaller crystals on a matrix,with a partial coating of black bitumen.7. Dense cluster of translucent sulphur crystals on a matrix. Thecrystal surfaces have a silky lustre because they are made up ofmicroscopic parallel crystal faces.8. A large etched sulphur crystal (right) and a smaller sharp angledcrystal (left) jutting up from a base of small crystals.9. A large, well-formed sulphur crystal with superb lustre andtranslucence. It exhibits hopper growth, which is when the crystaledges grow much faster than the faces; this gives the crystal ahollowed-out appearance.10. Yellow-brown sulphur crystals in parallel orientation. -- source link
