Made in USA TechDiamondTools polishing compound is a go-to tool for lapping, polishing, and sharpening. It’s oil-based and has no color additives. The former facilitates faster cutting, and the latter makes it safe for materials with high permeability. Another beneficial feature is its versatility. Use it both for manual and machine polishing; to lap and polish metal, glass, ceramic, and stone surfaces. Furthermore, a diamond paste is the most suitable compound for sapphire crystal and tungsten carbide polishing. Whether one needs to polish a gemstone, sharpen a knife, or remove a scratch, TechDiamondTools polishing compound will perform each of those tasks and even more.

    works great on glass surfaces. My apple watch polished like new all scratches gone.

    200,000 (H) Grit
    100% this takes a fresh cured resin piece & not only gives it a smooth surface like silk but magnifies the shine & of the iridescent colors underneath when using a holographic or iridescent glitter in the resin. Like the Parmesan Reggiano finishing touch to the pasta dish – it’s ok without it but OMG! The final touch makes all the difference.
    I’ll send you picks over the weekend & yes a whole different market than your original intent needs you & the containers you use are clean easy & allow the smallest amount used.

    I am an amature lapidary who only just started working about a year ago. I began using TechDiamondTools diamond polishing pastes at that time. I have used most of their available compounds, from 44 micron (400 grit) to 0.1 micron (200,000 grit), and have had great success with them, even though I’m still very new to the craft. I have used their products on a very wide variety of materials, including acrylic plastic, granite, quartz, agate, tiger’s eye, aluminum, copper, brass, zinc, titanium, steel, tungsten, and a great big 40mm decorative cube of solid tungsten carbide (which is a wonderful geek present for a chemist like me). One noteworthy piece (besides the WC cube) is a zinc plating anode ball that I cut in half, polished, and then etched with HCl to show the metallic crystal structure. In every case, from soft plastic to ultra-hard engineering material, TechDiamondTools diamond pastes have worked exceptionally well.

    5 Stars – Excellent paste and fast delivery.
    I use 5000 Grit for finishing high end cutlery on a Buffalo skin strop, with the smooth side up.
    I spread a VERY light coat on the slightly heated surface of the strop until just the reflection of the diamond compound can be seen in bright light. A little goes a VERY long way.

    Ordered the 3K, 14K and 50K paste in the 50% concentration and I’m
    getting great results using a smooth veg tanned leather strop I made
    myself. I put a pea sized dot on the leather and use a single edge
    razor blade to spread it out. My knives and tools remain hair popping
    sharp after a few strokes on the strop after each use. I’m using the
    50K ultra fine grit to strop my disposable razor and I’m still using
    the same blade after almost three months! Great products and I’ve
    recommended your company to many friends and family members. I’m sure
    I’ll be buying more but it lasts so long that it will probably be
    awhile before I need any!

    We love your product. We are polishing aluminum with 3000 Grit and it helps us cut polishing time way down from our previous process. It
    has been really great.

  7. Jerry C. Reich

    Where has this been all my 50 years of knife sharpening??!!
    This product is SO MUCH easier to apply to either my leather strop on a board or on the leather loop on a sanding machine.
    And it works GREAT!
    I am so glad to have found this product!
