Hi All Just started a piece of Cristinite in an Emerald cut. But it didn't go well. I have the angles, indexes etc but no instructions so did what I thought seemed logical. Pavillion end facets points just don't meet. Can anyone point me to some good instructions on cutting rectangular stones...

I am using a 1200 diamond lap for the final cut prior to a 3000 pre polish on copper. The 1200 seemed to be leaving scratches but I wasn't sure if these were left over from the 600 diamond lap. Anyway, I made sure and noticed that new scratches are definitely appearing with the 1200 lap. I am...

Hey guys. I charged a copper prepolish lap with 3000 using olive oil and used in to do my first stone. It worked fine. When doing the second stone it didn't seem to be working as well and I seemed to get some fine scratches. How often should I recharge a prepolish lap? How do I tell? Should I...

Looking for 64 index designs I am finding a lot of designs with fractional angles. For example, a standard brilliant with angles like 42.3 or 19.8 for the crown. On my old manual machine which has simple manual marked angles it would be impossible to set the angle to fractional amounts...

I have watched a couple of videos and read a few articles and am a bit confused with copper laps. So far I am using diamond laps but they seem a bit harsh so thought I would try copper. Anyway, I am confused about using water or not using water. I noticed that when charging a copper lap with...

As I am in Toowoomba it would be great to find a few close fossicking spots. Mainly for faceting materials. Anybody know of any?

Update on that old faceting machine I posted about. This is the first stone (CZ) and it's not good. Facets don't all meet. Something went wrong with the girdle and the culet broke off when taking it from the dop. I left the girdle thick on purpose to give me a bit of play room. But hey, I'm a...

I have finished cutting and polishing the pavilion of a stone and now need to transfer it. The first flat dop stick is glued on with super glue. I glued up a cone dopstick and was trying to take off the first dop stick but it stubbornly stayed in place and the second dop stick came off. I was...

Keep coming across these terms but can't see what the difference is. Is it in the quality of the cutting? I understand Competition cutting is extremely demanding and everything must be as perfect as possible. Does that mean Production cutting is acceptably of a lower quality? Such as meetpoints...

Hi All Not new but been a while since I did any real fossicking. Mainly for gemstones and a little relic hunting with a metal detector. Just having a go at faceting and purchased an old machine that seems okay. Yet to try it. Did post asking about its make elsewhere. Anyway, look forward to the...

Hi All Just came into this machine and would like to know the brand if possible. I would like to see if parts are available or at least buy a couple of extra dop sticks. Also wonder if anybody has successfully added a speed controller to a machine like this. I am told it is not possible with the...
