And here is a large Black Obsidian sphere with 65mm diameter. They all look almost the same so will intuit the best for you from our stock. Some may have little lines which helps prove they are real and not glass.
This size is often selected by those wanting the energy help for a room as it evenly sends out healing help in all directions. And then do some deeper inner work when held to integrate the shadow self so one feels whole and happy within themselves.
The photos shows reflections and dust particles of two different spheres. Pair it with the large size stand to hold it safely. We have black obsidian sphere of various sizes at the shops.
