Thanks. I like the icosahedron with the hieroglyphs.

That's an astrology d12: those are the sun signs or whatever those are called. The stone for that one is "blue sandstone". In person the stone has odd depths. The gold flecks are such that they give the illusion of being layered. Quite nice.

The d4 is a stone I can't find the English term for: it's literal translation is "natural black wood grain gemstone". It *might* be a petrified wood, but if it is it's smoother and more amorphous than any of those I've ever seen.

The d6 is blue turquoise (sintered, obviously: a real chunk that size would cost more than a car!), the d8 is a brown tiger eye, the 0-9 is lapis lazuli, the 00-90 is something that translates as "red sandstone" -- it's gold-flecked like the blue one -- the d12 is opal, and the d20 is green malachite.

The d6 with the weird glyphs in the foreground is something translated as "colourful jade" and that's one half of a pair of Tibetan divination dice. (The other half is still being etched. It will be made of "egg yolk opal".)

Yep, the hieroglyphic dice have pentagons for faces = 12 sider.
