Transparent Pricing for Your Stone Processing

So you can understand exactly how the costs for finishing your rough stones and personal finds are calculated, I work with full transparency. Every stone processing service – whether sawing, lapping, grinding, or polishing – requires craftsmanship, individual preparation, and the precise use of professional machines and abrasives.

Why Are There Setup and Operating Costs?

Before I begin the actual processing, each workpiece requires time, care, and high-quality materials:

  • Setup & preparation times: Every stone is unique. Before sawing, lapping, or grinding, I measure, align, and clamp each workpiece individually and securely on my machines.
  • Multi-stage lapping and grinding process: To eliminate saw marks step by step without a trace, I lap the stone in a precisely coordinated process, working progressively with high-quality silicon carbide from coarse grits (F80 to F220) through to fine grinding (F360 to F400).
  • Exclusive polish for hard stone: The final stage is my polishing process, precisely tailored to the extreme demands of hard stones (such as agate, jasper, or quartz). The result is a mirror-smooth deep gloss and colour brilliance that clearly surpasses standard polishing results.

How My Online Calculator Works

My calculator guides you step by step to an indicative price for your workpieces:

  1. Select service & mineral: Specify which processing you require and the type of stone (soft stone vs. hard stone such as agate or jasper).
  2. Cut rough stone into slices: Would you like a rough stone cut into slices? Simply enter the dimensions. The calculator automatically accounts for the first facing cut (4 mm) and the material removal by the saw blade, and calculates the maximum number of slices.
  3. Grinding & polishing – freely selectable: If you have slices cut, you can flexibly choose the finish:
    • Cut only: You receive the raw saw slices.
    • Including grinding & polishing: With one click, you can add lapping, grinding, and polishing for the cut slices – from a fine matte finish to a brilliant high gloss.

How Are the Costs Calculated?

  • Setup fee (€4.00, one-time): Charged once per workpiece position for grinding/polishing – regardless of whether 1 or 10 slices are processed.
  • Cleaning fee (€3.00 per slice): After each individual lapping step (e.g., when switching from F220 to F360), each slice is meticulously cleaned by hand to prevent coarse abrasive particles from being carried over into the finer polishing stages and causing scratches.
  • Surface price: The actual processing cost is fairly calculated based on the real surface area (in cm²) of your slices.
