Rainbow obsidian and a sapphire bomb

[shivan]

Was lucky enough to be given a piece of rainbow obsidian to slab recently. Not having seen any before i did not know what to expect. It looked grey (except where i had been knapped where it looked like black obsidian) with a sharkskin like texture and flowbanding. First slab did not show much, but colour started showing through on the second slab and the third had beautiful banding showing.




Also had a bit of a play round with a sapphire bomb. It did not come up too badly, but cleave plane seems to spoil the polish a little.

Looks good Ian you should get a few slabs out of it mate they should polish up a treat

the bomb is almost like a star saphh

I got 1 slab with color and the end piece which i should be able to get another slab or two, will see how it polishes first.

The sapphire cam up ok, but the cleavage seems to have a bit of a weird effect, not sure if i was ment to angle it a bit more.

Try rolling it around in the light mate and see if it has a star

It does not have what i recognize as a star (cross) but it does have a fibrous sheen in a few places that would have been a star if one was there? Its a bit hard to explain.
