    Diamant Cast-Iron Manual Grain Mill is currently on backorder.  Due to a delay in the supply of raw materials, we are currently unable to advise of the expected delivery time. If you choose to complete an order now, it will be sent to our warehouse immediately, ensuring that your order will be fulfilled as soon as the new stock arrives. Note: 

    Massive strength and careful engineering make the Diamant Grain Mill one of the finest hand-turned mills in the world.

    After analyzing dozens of mills, this one emerges head and shoulders above the rest. It is beautiful, high-performing, and, since it is made entirely of cast iron, it will far outlast lighter aluminum mills. The Diamant is equally at home in a farmer's barn cracking bushels of corn for livestock, or in a baker's kitchen milling fine flour for delicate pastries.

    Unique Pre-Grinding System for Superior Results - Only the Diamant has it! Several blunt pre-grinding "teeth" gently mash grain. When it gets to the auger it's perfectly prepared for a smoother, more even grind. Competitor models use an impractical spring arrangement that's not nearly as effective and completely lacks the elegant engineering of the Diamant.

      • Grinds fast and fine
      • Grinds virtually anything (without the need of additional augers)
      • Easy to use
      • Solid cast iron - built to last with little maintenance!
      • Quality-made in Poland

    Grinds fast and fine - Extra large burrs churn out flour as fine as store-bought 20% faster and much more easily than any other hand-turned mill on the market.

    Grinds virtually anything - Corn, beans, and most oily materials can be ground without using a special auger. Grinds all grains, many spices, legumes, beans, nuts (except peanuts) and seeds without changing burrs! Make flour, meal, coffee, sesame tahini, cereal, or animal feed. Specially engineered iron/steel burrs grind just as fine as other mills' stone burrs – and they eliminate stone grit in your flour.

    Easy to use:

    • Big V-belt flywheel is made of solid cast iron, not aluminum. Adds momentum to the turning action, rotates smoothly, and makes it easy to motorize.
    • Adjusts quickly and easily from powder-fine to coarse.
    • The long wooden handle lets you use two hands for more leverage. Or share the work with a friend (face each other). Grinding is much easier - and more fun - with two people.
    • Bushing/sealed bearings eliminate maintenance - never need to be oiled!

    Built to last - This mill hearkens to an earlier time when things were built to outlast their owner and be passed on to the next generation. Solid cast iron mill is one of the heaviest hand mills in the world. Non-toxic green finish with gold trim, force-feeding worm auger pre-mashes grains, three kinds of burrs adds versatility, one-year warranty.

new grinder

Received grinder theres some paint chipped off fly wheel ..other than that it works great

Matthew S.
Solid made product

This is a solid made product! My only concern is that the fly wheel was not prepared before it was painted. The spokes that radiate out, have jagged edges produced during the casting process that were not sanded smooth. It was just painted. It doesn’t affect the performance; just the appearance. The rest of the main body was cared for and prepared.
Also, they send a wrench and screw driver with mill. Pretty thoughtful!!

Built like a tank

I'm very pleased with my Diamant D525 grain mill. Extreme Wellness have to best prices. I recently ordered the fine grinding burrs, Extreme Wellness was $96 less than Layman's.

Beautiful addition to our home- it will last generations

I am relatively new to using the grain mill- but have already made a loaf and pasta with home milled flour. Amazing flavor! There are a lot of flour types available in the supermarket (other than all purpose white/whole wheat), but by the time they leave the commercial mill and reach supermarket shelves, it is often not fresh… it has lost that nuanced flavor gem hiding in the grain. Fresh milled is simply better tasting, and some say better for our health. I can’t speak to a health boost, but the flavor enhancement has been great.

As for the mill, I did a lot of research, read way too many reviews over a few months, and kept coming back to the Diamant. The cost is huge, especially if you go for the extra plates (worth it), but as they say you get what you pay for. The construction is rock solid and full cast iron as described. The biggest challenge confronted with any manual mill is the user output needed to turn the mill. I won’t lie, it is a little work, but the massive fly wheel (both in weight and diameter) makes this mill very easy to turn- I think anyone could work the mill easily and should not be a deterrent. From what I can tell, is the easiest out there. In terms of speed, it is very quick to turn out a cup of flour, probably about a minute of milling, slower the more fine the final product. The mill seems super consistent once the size is set, though you do need to turn the flywheel while adjusting with grain in the auger, or else it won’t dial properly.

One complaint- the paint chips easily. The paint is not adhesive- which means it doesn’t bind the primer so it comes off surprisingly easy. In time, it will show its wear, a testimate to its use I suppose, but still something that shouldn’t be a problem considering the cost. I plan on taking one of the pieces to an auto body specialist to see if I can get a paint match that I can dab on as needed.

For me- it ultimately came down to the esthetics of the mill, and it’s lasting design. As a permanent fixture, it is in my opinion, beautiful. From a longevity standpoint- it will last a generation. After I teach my daughter how to really make bread- I hope she will one day take the mill to her family, and do the same.

Better than I thought

i knew I had ordered a quality grain grinder, but the weight, materials, and quality really pleased me, more than I thought it would. We set it up and gave it a try and out came perfectly ground spelt. I have used electric and other hand grinders in the past 50 years, but this is the highest quality hand grinder I've ever seen. and the large hand wheel makes the work so easy! I am 69 and could grind grains with this grain mill easily for quite a while. Wish I'd had this years ago!
