Which Voodoo Faceting Polishing is Right for You?

About Diamond Polishes

It is important to understand that finer diamond particle size does NOT always mean a finer finish. At larger diamond particle sizes, the diamond plows through the softer stone being cut, scratching a furrow and removing material in an abrading process. However, at smaller diamond particle sizes, the scratches stop scraping material off the gem, and begin instead to shove it out of the way in a ductile manipulation process.

Ductile manipulation induces strain in the very thin layer being operated upon. That strain may invite microscopic cracks or may make the surface more vulnerable to tiny scratches, which can relieve the strain a bit. This is why some materials (or individual facets of individual gems) may show a cleaner sharper finish when polished by larger-particle-sized diamond polish than when polished with smaller-particle-sized polish – and why they may appear nicer yet when polished with Oxide polish.

This kind of behavior is most obvious in Quartz, but may be noticed in other materials as well. If you want to create the best polish, experiment by polishing every other facet with one polish and then finishing the others on a different one, and compare them under a loupe. In my experience, many materials will polish more nicely (as well as more quickly) with 14k diamond than with 50k or 100k. In my work, I will usually test the larger diamond first and work my way down to a finer grade if necessary.

Diamond-based Voodoo polishes will work on almost any gem material from hardness 4 to hardness 9+, and Voodoo Oxide polishes will work on a wide range of gem materials as well – including some of the more exotic ones. I hope the following details will help you select the Voodoo products that best suit your needs. If, after reading this information you still have questions, shoot me a question and I’ll be happy to give my recommendations.

1200 Voodoo Carving Paste

Voodoo 1200 / 15-µm carving & concave-cutting paste: This SUPER FAST AND SMOOTH paste, used on a Copper mandrel, will cut almost as fast as a 600 metal-bonded lap, while leaving a very smooth finish, so you can get quickly to polish. I use this paste for both gemstone carving and as the primary grit for concave cutting. Use on Copper, Corian, BATT, etc.

 

Voodoo Magic Carving Polish 2k prepolishVoodoo 2,000 / 9-µm prepolish: This INCREDIBLY FAST prepolish cuts as fast as a 600 (red) Newbond, but leaves an even slicker finish on most materials, requiring very little work with any of the Voodoo polishes to complete a competition-grade finish. This prepolish won’t under-cut on finicky materials like Corundum, Spinel, or YAG.

 

Voodoo Magic Carving pre polishVoodoo 3,000 / 6-µm prepolish: A VERY FAST and FINE prepolish that  cuts about half as fast as the 2,000 – still way faster than a 1200 (blue) Nubond lap, and leaves a finish good enough for girdle polishes. It requires so little touching with any of the Voodoo polishes that you can cut the meets “on” with this and the final won’t usually visibly move them.

 

Voodoo Magic Carving prepolishVoodoo 8,000 / 3-µm prepolish: A a special-use ULTRA-FINE prepolish, for carving and concave work; for huge facets; and to work with troublesome materials.

 

 

 

Voodoo Magic Carving PolishVoodoo 14,000 / 1-µm polish: This is my VERY FAST polish that makes it easy to adjust meets, moving them almost as fast as a 1200 Nubond (blue) on many stones. This is the work-horse of Voodoo Diamond polishes, and will leave a very nice finish on most gem materials between hardness 6 and 8. For most polishing tasks, I recommend this one first.

 

Voodoo Magic Carving PolishVoodoo 50,000 / .5-µm polish: This is a VERY FINE polish, still fast and can move meets around. It can still be used directly after 600 metal-bond cutting on smaller stones, and can still drift meets in easily. This compound will polish most materials hardness 4-6 and 8+ without leaving any haze or drag marks.

 

 

Voodoo Magic Carving Polish

Voodoo 100,000 / .25-µm: This is an ULTRA FINE polish for those stones that require super-fine diamond. This polish is recommended only for faceters experienced withi 100,000 mesh.

 

 

 

Voodoo Black Magic Carving PolishVoodoo BLACK MAGIC 14,000 / .75-µm polish: This is a very special formula polish using ultra-sharp friable diamond. It cuts and polishes very fast, yet leaves a really premium finish on most gem materials between hardness 6 and 8. I use BLACK MAGIC on finicky stones, or when polishing on cleavage planes of stones like Topaz or Spodumene, or when polishing really large facets on precious materials.

 

Voodoo Black Magic Carving PolishVoodoo BLACK MAGIC 50,000 / .375-µm polish: This is a very special formula polish using ultra-sharp friable diamond. It remains fast and can move meets around and  will polish most materials hardness 4-6 and 8+ without leaving any haze or drag marks. This BLACK MAGIC was my “secret weapon” polish for several years, available only in very limited quantities and for a very premium price. Due to many requests, I’m making it available as a standard product.

About Oxide Polishes

Oxide polishes operate in a chemical rather than abrasive fashion to manipulate the surface of the facet. For this reason, they do not induce surface strain associated with ductile manipulation by sub-micron-sized diamond particles. This is especially important in Quartzes, but may also show superior appearance in other materials.

Oxide polishes have traditionally been very messy to work with – and challenging for faceters, who almost universally tend to use too much polish and water – resulting in a variety of undesirable results from balling-up of polish and scratching, to drag marks and rounding, to simple failure to polish.

There have been a variety of strategies to try to address those issues, including embedding oxide polishes in resin laps. Voodoo Oxide polishes use a special Voodoo base that is used to coat the surface of a lap, holding the polish flexibly in place, preventing it from slinging off, including a lubricant to prevent heat build-up, and allowing just the right amount of water to cling to the lap so the chemical process is properly catalyzed.

Use Voodoo Oxide polishes with a very light mist of water applied with a hand pump mister like a hairspray bottle or a perfume atomizer. Mist a nice cloud above the lap and let it settle onto the lap – just enough to feel the friction increase dramatically. Maintain a very light dampness in this way, and experiment to discover the optimal amount. Polishing with Oxides is more complex and challenging than polishing with diamond, but it is an essential skill if you cut Quartz.

 

VOODOO “Q”: This is an older oxide-diamond hybrid polish, originally intended for Quartz, but which proved most effective at polishing Beryls very quickly.

 

 

 

VANILLA VOODOO: This is a new oxide-based Voodoo that is used very sparingly on all the same kinds of laps that you usually use Voodoo on. As an oxide, it requires water – in a very light mist – to activate the magic between this polish and the gems. This is the result of years of research and development for a “magic bullet” for polishing Quartz quickly and painlessly. Use at slow speed.

 

VOODOO WET CHROME: This is a special Voodoo base with a rich charge of Chrome Oxide. It offers all the advantages and versatility of Chrome polish, without the usual mess. The Chrome remains trapped in the base and locked to the lap, while you apply a very light mist of water to facilitate the chemical polishing. Voodoo Wet Chrome can be used on a huge variety of materials (including Moissanite), and due to the unique formula, can even be used at high lap speeds.

    I bought the vanilla and chrome polish, but they are not working for me. I work a lot with Topaz and the Chrome just is not working. I am misting the lap and running the lap at high speed. Any ideas?

      Hi, Ken,

      I understand the frustration with polishing. Even now, when I’m frustrated with faceting, I guarantee it has to do with polishing something. And, I hear that from my colleagues as well.

      There are many factors to polishing technique, including pressure, lap speed, speed of sweep, amount of polish used, etc, etc.

      AT THE ACADEMY, WE TEACH EIGHT SPECIFIC COMPONENTS OF *TECHNIQUE* ALONE.

      You didn’t mention the type of lap, which is half of what we call polish-lap “recipe”. I use Voodoo Oxides on both Corian and Darkside laps – and occasionally Wizard lap – with success.

      Also, “not working” could mean many things – from nothing happening at all, to polishing too slowly to tolerate, to orange peeling, stripping cleavages, polishing unevenly, rounding facets, or leaving scratches.

      If a polishing system (recipe and technique) is leaving scratches, the nature of the scratches gets into another vast list of possibilities of what that could mean – furrows, streaks, groups of scratches, isolated cat-hairs, etc.

      I do not think Vanilla will work on Topaz AT ALL. I would not even try it myself.

      Chrome would not be my first choice for Topaz, because Topaz responds so quickly and so well to diamond.

      If I had a Topaz that was troublesome with diamond, I may go to Chrome as a work-around, though.

      I recommend double-checking the video on the YouTube channel about using Voodoo Oxides – lap charging, etc. The most common mistake in using Oxides is using too much. You need VERY little – less than most people think. Too much causes various versions of “not working” to manifest…

      The above is intended to get you thinking about the POSSIBLE list of factors involved – and to being experimental with them, varying one component at a time. This is the CRAFT of faceting, btw – experimentation. Even today, with all the polishes I have and use, I’m testing two new polishes in the studio!

      Usually, the above line of conversation gets a person into an experimental frame of mind enough to find and resolve the issue.

      If you continue to have frustrations, feel free to e-mail with really SPECIFIC information about the polish-lap recipe you’re using, and the specific aspects of technique that are producing identifiable unique outcomes.

      From there, I can probably help you troubleshoot the issues.

    dear John, I have always been using cerium oxide to polish emeralds, do you have any better idea?

    • John Bailey says:

      Hi, Frank,

      There are many different ideas about this. One problem with Cerium on Emeralds is that it can pack the pits and cracks typically found in that species. (And, it’s slow)

      I personally use Voodoo on Emerald most of the time, partly because the Voodoo polishes very quickly and also is easy to wash out of pits with the typical solvents we use to release the Emerald from the dop. Of course, that strategy is assuming the Emerald to be untreated with resins or oils that the solvents could remove…

      One of the best strategies for Emerald is the Greenway (and probably Creamway) laps by Gearloose – and sold here on the Academy site. These laps have aggressive oxides embedded in the laps, so they can’t embed polish into the cracks in the gem. This is particularly useful for doing repair work on Emeralds where you don’t know the treatment status. So, I personally would use the Greenwing lap for Emerald repair work.

      Hope this helps!
