Instructions
A. Pavilion
1. 90.00            04-28-36-60-68-92    Determine the location of a girdle.
2. 55.78            04-28-36-60-68-92    Formation of a temporary culet (see note)
3. 58.00            96-32-64                    Meet the culet two temporary
4. 90.00            96-32-64                    1-2-3 Meet
5. 46.99            05-27-37-59-69-91    Meet 1 and 3
6. 48.88            02-30-34-62-66-94    1-2-3 Meet
7. 53.12            04-28-36-60-68-92    See note
8. 46.34            03-29-35-61-67-93    Meet 5-7
9. 42.90           02-30-34-62-66-94                 Meet 6-8
10. 41.50         04-28-36-60-68-92                 Meet 5-8

Note: the facet 2 is first cut at 55.78 degrees and forms a temporary culet. This will allow the facet 4 (girdle) to be cut and located to the right place. Later, the two become the facet 7 when it is resized to 53.12 degrees at the intersection end.

B. Crown
1. 38.00            96-32-64                    Determine the height of the girdle
2. 37.39            04-28-36-60-68-92    Determine the height of the girdle
3. 34.28            01-31-33-63-65-95    Meet 1 and 2
4. 33.79            03-29-35-61-67-93    Meet 1 and 2
5. 33.95            05-27-37-59-69-91    Meet 2 and the girdle
6. 25.53            03-29-35-61-67-93    Meet 4 and 5
T.                      Table 0.00.
