SHHHH! Don't spread it around, but I have been having an affair for the past few years........... with Obsidian. Don't tell my wife!!!! Here is an elongated egg that has Gold Sheen. I believe it is from Mexico.G ![]() This one shows a purple eye that moves across the surface as you tilt it. It is from Davis Creek.  This is an unmounted cab with the eye in the center.  Tilted one way.  Tilted the other way.  This is a large one with inlayed Opal, Black Obsidian dividers and silver.  This is a double cab of Davis Creek. One side. (With lint)  The other also with lint.  I'm working on a tutorial on how to orient and cut Davis Creek material so the color will end up as an eye. Anyone interested? Thanks for looking. Bob |

Purple Davis Creek?? That place has the most amazing obsidian. I still need to work the green sheen you gave me and will get to it one of these days. Also need to dig at that place someday. Looks like an amazing place.
OK now you have done it, inlay opal with obsidian. A bar has been raised that will never be repeated! That is definitely AWESOME!

I'm sure your wife would agree with your affair if she would wear those beauties.
That big cab with inlays of opal, black obsidian and silver is a work of art! You presented it along with another cabs that are, of course beautifull, but I think he deserves more attention. What is that beauty going to be? A broach, a pendant? Any story of its making? (If it's secret, that's OK).

Adrian,
The large inlayed piece is made of three pieces of Obsidian. The back is a solid piece about 1/4" thick. the top is made of two similar colored pieces. I cut a large notch in each for the center piece. I made the square of silver and added the silver at the junction between the top pieces. I then cut the center Opal, made a bezel and placed it in the center. I made some narrow strips from Obsidian to separate the Opal inlay. I then shaped the inlay pieces and glued them in. The final task was to grind and sand all of the pieces level. After I was finished I regretted not using more colorful Opal. One of the problems with Opal in thin pieces is that it loses color as it dries out. I might replace the Opal sometime in the future.
I rarely make these items for a specific use other than things to put in my Club display case. Sometimes I make jewelry out of the cabs.

On the flat surfaces I sand them dry with a worn 220 and then a dry 400, then to polish on a carpet covered wheel with Cerium Oxide. On another thread I have a tutorial on polishing Obsidian.

Just beautiful all of them and that inlay is amazing. I read your tut in the other thread and was wondering if your polishing technique for obsidian could be applied to other stones? Your tut seemed easy enough for a beginner to try keeping in mind to not let it over heat.
Thank you for the pics and the tut.

sitnwrap,
Yes, I use the same method for slabs and geodes, except the sanding does go a little slower on harder stones. Also, I will go to a 400 grit sanding step before going to polish.
