Just for info, im rendering this pic at 'super' with maximum ray depth 20 and tir of 18. Its been rendering for a day and half most of the time. Its render resolution is 1600x1200 but ive dropped down this partial render size. On my 1.2 thunderbird this is taking forever, even when finished i want to attempt to remove those tiny spheres in the middle and see if i was re-render just the egg shape on left with 0 reflection. If i can ovoid redoing the whole scene i will. The 4 replicated diamonds in the make even this fairly fast cpu choke. I recommend you try making a scene with lotsa glass and volume textures and you might reconsider the speed that you think bryce has.
