Gem faceting

[Double E]

I managed to find some silver white heated zircons which are quite inexpensive and clean. Just wanted to acquire a pcs or two for later cutting as they should cut beautiful gems given their dispersion.

I have also in mind some other relatively cost friendly stones like electric blue topaz, ana Madeira citrine. I also come across something called Ox blood citrine, am not really familiar with this species.

Returned to cutting today. The OEC.
Cutting those facet A. I think it kind of ruined the symmetry of the crown, which I thought was not bad last time after I cut and adjust facet B and C.


Nearly all the points of facet A failed to meet and align with B and C, as you may see in above pics. Apart from I am still cutting crown first for this stone, I believe setting the angle of facet A not patient and accurate enough was another main reason. Most facet A are leaning towards left. I made use of polishing to fine tune those facet A to some extent, but things were still off.

I also witnessed the difficulties to polish as you guys mentioned. This is a ametrine. I found it easy to be scratched.
