Carbon Included Enhydro from Tibet DX3825 goias Welo Opal is often cut

Welo Opal is often cut into various shapes

chemical reactions

The coloration is attributed to various mineral inclusions and trace elements that were present during its formation

and the brown barite is chatoyant as well as phosphorescent

its geological significance remains a subject of ongoing research

Carbon Included Enhydro from Tibet DX3825 goias Welo Opal is often cutCarbon Included Enhydro from Tibet Approx. Dimensions: 3x1. 25x1 inches Approx. Weight: 74. 2 grams Locality: Tibet This is a completely natural double terminated crystal from Tibet (no polishing has been done). Carbon is included in this quartz piece in several places, but most notably in a pocket with a fluid inclusion. This causes the carbon particles to cascade up and down the cavity. The cavity is circled with black Sharpie, which can be removed
