Stone has some small surface reaching bubbles that filled with CeO. Suggestions for best way to remove.

Paul, nice job.
Being quartz and looking very clean a ultrasonic and or jewelry steamer is an option. Soaking it and some pressured air as well.

I already posted a couple of these, but this is most of my cutting from the last while (in the case for a harmonica, lol).

From top left, going clockwise (EDIT: I posted the pic upside down, so from bottom right, going clockwise)

An unfortunately included and poor saturation bicolour tourmaline... where I also accidently didn't cut the c-axis oriented facets deep enough to avoid colour mixing,

Lithium Tantalate barion cushion,

Pink tourmaline, pavillion only recut,

Green zircon,

Garnet (with a 1.72 RI) with a Superman's decal-ish outline,

Aqua with a pope-hat/motorboat outline,

Aqua (not a recent cut) in an elongated trillion

Good work - a great collection! =D>
I really like the ametrine rectangle too - in which design did you cut that?

Woops. This isn't even the off the dop thread. I need to have my coffee before posting in the morning

Martine: the design is Jeff Graham's classic (at least for faceters) Smith bar: https://web.archive.org/web/20120406110 ... hbar.shtml
