| Description |
A fine reference floater crystal of deep indigo blue Sapphirine. This piece displays an intriguing surface texture which indicates the progressive lateral molecular growth of the crystal along its front face, showing beautiful geometrical patterns that match the hexagonal shape of the euhedral crystal similar to "record-keepers" on a quartz crystal. |
