46 x 19 mm, opaque shading from a soft mauve to almost burgundy at the top, with yellow.  This is a form of Jasper that comes from Australia.

32 x 30 mm, shades of green ranging from almost white through sage to evergreen.  This stone originates in Madagascar.

41 x 29 mm, mottled tan and beige with some black.  From Oregon.

50 x 20 mm, like most agates bands of opacity and translucence, in very delicate shades of blue and white.  From Madagascar.

42 x 19 mm, scene-like banding in tan and beige and grey.  Similar to America's Owyhee jasper, but it comes from Africa.

40 x 20 mm, bands of green shades.  Very shiny stone.  From Congo, Africa.

41 x 20 mm, turquoise and brown.  This one really resembles turquoise.  Mined in the US.

26 x 19 mm, great shading from mahogany to opaque amber with some fine striations of hematite.  Mined in Australia.

41 x 32 mm, a gorgeous rare shade of sky blue with subtle, pretty mottling.  Mined in the US, and heat treated for stabilization.

36 x 26 mm, much darker than in the picture - it appears mostly the deep red color with some hematite banding and a hint of yellow that's not nearly as obvious in person.  Tough to photograph.  Mined in Australia.

28 x 20 mm, it has the opaque/translucent variation of many agates, but mostly opaque with little "windows".  I haven't seen many like this.

34 x 19 mm, opaque Caribbean blue with sandy webbing.  From China.

19 x 13 mm, a dark grey stone that has an iridescent blue flash when moved in the light... this is SO hard to photograph but so beautiful.  If you'd like a small, unique stone pendant this would make a great one.  It's probably small enough to be a ring, too.
