[QUOTE="Badge, post: 639674, member: 21082"] Thanks for the advice Pat Hogen. I was trying for a smaller table but ran out of stone. I did read quite a bit about cutting topaz and what I read was fairly confusing. The critical angle is 37°? Most designs have pavillion and crown angles more acute ( or is it obtuse? ) than 37°, ie 42° 52° etc. If the stone is wide and I use those angles there is no way I can fit that design. So I'll look at the Sunburst, Portugese and Scintillator designs to see if I can fit the other piece in. I only have the 64 index atm otherwise I'd try the Princess cut. That's one for down the road. Thanks again. Cheers. Badge. [/QUOTE]
