Novice stone for 2005 USFG competition
This is a good stone to develop your basic skills on. I chose synthetic spinel for my material. I started out with a 360 crystallite lap for rough in. I used 44 & 41 on the pavilion. I first cut the 44 close to a point and then squared it up on the 90 to about 13 mm all with the 360. I put a 600 on and brought the stone size into 12.3mm and then brought the 44 into just making a point. I put a 1200 on for my pre-polish, brought the stone size into 12mm and then followed the break line @44 around to meet. Then I cut the 41 in at 95-01-23-25-47-49-71-73. I only brought them into about 1/16 of an inch to corner point as I will polish in the rest of the way.
Sometimes if you cut all the way to the exact corner when you go to polish, it will get to meet point before the whole facet is polished. In this case it will work. Sometime you cannot do it this way but that is another story.

I polished with 50,000 on Batt and it went fairly quick with no problems. At this point I have three hours in the stone and it is ready for transfer.
After transfer I used a 360 to get rid of some material. I cut to approximately ¼ inch girdle line on the 4 sides at 48 degrees, put a 600 on and followed the girdle line around again. It was off by ¼ degree on the cheater so I continued cutting the rest of the stone up to the table.
I put a 1200 on and set my girdle line a little over .3mm and made sure it lined up when I came around. C-2 cut fine, however you must be very careful cutting C-3 in as it takes a light touch. Now I cut the table in with the 1200, I over cut just a little and polished the table. Now I came back and polished C-1 and C-2 into meet points. I use C-3 to close all meets for a very nice close. Good Luck!!
