I have designed a few Lapis Lazuli slabs I purchased in India. These are Afghanistan Lapis, the best the world has to offer. The mines are long closed so I feel excited to have collected these.
This one is approximately 2.75" large. The Lapis, if the quality is excellent, must have pyrite inclusions. These marry together in the hundreds of thousands years of growing(stones grow) . The Pyrite is Fools Gold, showing speckles and arteries of gold . I enhanced this Lapis slab with gold colored brass Tibetan beads and finished with wiring in gold metal and copper wire.
