The fluorite crystal is 43mm across, it shows a really beautiful texture and uncommon blue-lavender color. The crystal size is exceptional for Tongbei, common material shows crystals in only 50% of this dimension. The crystal is isolated and exposed on the typical light matrix. In the lower half you can see a group of lustrous, dark brown smoky quartz crystals. Contrast is as good as it ever could be and the tri-dimensional assemble is even better in person. The fluorite is undamaged, the smoky quartz crystals are not completely perfect, but also in good condition overall. Minor Spessartine is also present.
