That's looking really good xcvator, spot on with the marking and cutting, and from what I can see in the bottom photo (bit small) those cabs are looking tops with a nice polish.
You're obviously getting the hang of your machine and it looks to be working well for you, very very well done. :clap: :clap: :fistpump:

It still has a bronze band of rutile that extends through the crown facets but sparkles under the work light well due to the lightness of the stone. Am looking forward to see how it reacts to the sunlight.

Wally69 said:It is a central Queensland party sapphire Doug, it has a wisp of bronze rutile through it that does some interesting things to the light reflections.
It could probably be called a colour change sapphire as it reflects green and gold wattle colours in the sunshine and yellow or green under different artificial light. It is a shame I cannot share the experience of how it behaves in different light conditions with you all.
Glad I persisted with this stone and made the decision to cut out most of the rutile.

I scored some old magazines At a garage sale that had an article on sapphires and it basically says I am stupid for not heat treating my rutile included stones layful: :zzz:
I think I will need to research and make myself a little heat treatment contraption. If anyone has experience would be keen to hear how you went about it.

Well Wally69, that mag is absolutely talking cr@p. In fact, in certain stones containing rutile, one will devalue it with heat treatment. You have to judge the stone for what it is. That's why I commented it's a very nice stone. Rutile or no rutile. Beats a black stone hands down every day.
I did consider cooking my self. And did a bit of research. GOL is a good resource. A basic oven was not cheap especially if you are considering using gases. I would suggest talking to Roughtocut (?) ex forum member. PM me if you require his number.
