This is about all I have shots of right now. I got this from the RockShed. I'll try to get shots of some of the other stuff I finished soon. I been out of service for a while, but though I'd better start posting at least something to validate my existance, Thanks for the outlet-     There doesn't seem to be much color in the stuff from the Rockshed, that goes for the Amythist as well. Shot outdoors doesn't really give a good representation of the shine, but I'll get some better shots next go round. |

Hey Banjo. Another great job. How long did they go for in the rough grind? They all have a nice shape to them. Come on, let's see more.

Nice job, Banjo, those are very nicely tumbled and look to have a great shine too. This batch obviously took time and care, and it paid off.
The Rockshed amethyst/citrine doesn't seem to have a lot of colour, but I think it works pretty well here, with a nice contrast of citrine and regular quarz in each stone. Do you know if their citrine is natural, or made by heating amethyst?...since it looks so much like their amethyst except for the colour, I'm assuming that they use the heat treatment?
Digital cameras can act funny with the focus under certain circumstances....through glass, with strong horizontal lines, etc., and I'm guessing that the same is true for your black background. So not to worry, you could just override the autofocus and manually focus if you wanted, and your camera allows it.
Looks to me like you took your photos in direct sunlight. In my experience, that is a poor choice for clear quartz rocks like amethyst, rose quartz and citrine, because it really highlights their internal fractures. If you haven't already, try taking some pics of them outside in the shade instead of sunlight. For me, that resulted in pics that were much more pleasing.
Nice show, I look forward to what else you have.

Oops, sorry about the focus comments...those were really meant for BShultz's (sp?) thread, which mentioned some problems with the camera focus on a black background. So ignore that comment in my last posting. Thanks.

Hello Banjo! I like the way they look, specially in the last photograph with more close-up details. I like their soft and romantic color, I think they will look great in a flower vase with some white roses, very nice indeed! ;D

rollingstone tell me more about the citrine - in natural form what color is it opposed to heat-treated forms? i didn't know you could heat the amethyst. what would be the reason you'd want to do that if you can get it natural without heat-treating? so it turns it from purple to yellow/orangish?
banjo i was admiring your workmanship and thinking back to when you were frustrated with your rocks. i guess you're over that now ;D. how's the faceting thing coming?

Hey Banjo,
They look great to me! I hope my batch I am working on now turns out half as good as those you finished look.
Thanks for the photo's

Rocky, As I understand it, most citrine on the market is actually heat-treated amethyst. That is for gemstones, I don't know if the same holds true for tumbling rough, but I presume so. Citrine often commands a higher price than amethyst, thus the desire for heat treating. Citrine does occur naturally when amethyst is heated by natural processes (or maybe forms at high temperature?), but it is not as common as amethyst, so heat-treating amethyst fills the gap. It is supposed to be hard to tell the difference between natural and "artificial" citrine...if there are inclusions in the amethyst the heat treating will cause fractures to form around the inclusions and that can be used to identify "artificial" citrine. At any rate, the colour is quite stable once it has been heat-treated, so it's not like it's going to revert back to amethyst or anything. The only temperature reference I've seen for this is to heat-treat amethyst at 450C (840F), so it's not like you can do it in your stove. But if you have a kiln.....

missed you around, Banjo, consider your existence validated.....
i thought some of the citrine had a lot of color, and a superb shine on all of them! i kinda gave up on cirtrine because of all the internal fracturing, but you made them come out nice despite that.
how long in the coarse grind? what polish did you use?
good to have you back,
KD
