Ah spring madness! Having used the incredibly fast and powerful new zirconia formulation that Jon Gearloose Rolfe just made cutting a Madeira citrine, I decided to ask him to make me a dual lap. I am a huge fan of dual laps, prepolish to polish on each facet. Very very fast.

Now zinc outer band combined with the cream way center even better.. Add 13k pcd diamond to the zinc, and I'll be done with a few hands waves and muttered incantations.. Greased lighting. I'll break it in with a 15 carat tanzanite cut in the 115 facet barion cushion 2 by brother John Bailey, one of my favorite designs.. Stay tuned!

That was a technological update to the Creamway and Zirconia polish courtesy of Adamas Instrument going back a few months.
Tanzanite should polish very quickly with the updated Creamway, but I give you a caution for Tanzanite that was cooled too quickly after heat treating for color. Those stones can crack rather easily. Use plenty of water and keep the rotational speed low.
