Diamond-Point Engraving - A Different Approach to Portrait Work on Stone

Most people picture laser cutting when they think of automated stone engraving, but there's a mechanical alternative that's been quietly gaining traction in the monument and memorial industry: impact engraving with a diamond needle. Rather than burning an image into a surface, this method physically chips away microscopic amounts of stone with thousands of controlled strikes, gradually building up shading and detail the way a halftone image is built from dots. The Master Stone engraving machine, made by Lithuanian manufacturer MPrint, is a well-documented example of the approach in commercial use.

Why the Mechanical Method Matters for Dark Granite

Polished dark granite is the material of choice for most modern headstones and memorial plaques, but it's also notoriously difficult to engrave with strong visual contrast. Diamond-point impact engraving addresses this directly: the chipped surface scatters light differently than the surrounding polished stone, creating a bright, high-contrast image against the dark background. MPrint describes the result on dark granite as producing "an absolutely fantastic contrast," which is precisely why this method has become closely associated with memorial portrait work rather than general decorative engraving.

The Master Stone supports three engraving modes — point, amplitude, and combined — giving operators control over how fine or bold different parts of an image appear, which matters for reproducing photographic detail like facial features and shading gradients.

Specifications Worth Knowing

The machine handles a working area of 700 × 500 mm with an adjustable engraving depth of 0.1 to 0.5 mm, connects over USB or WiFi, and runs on Windows 7 through 11 via included software. Because the unit sits on top of the stone rather than requiring the stone to fit inside a fixed bed, it can be used on larger or irregularly shaped granite pieces without the size restrictions common to enclosed engraving systems.

Practical Applications Beyond Memorials

While monument work is the core use case — headstones, memorial plaques, and portrait inscriptions for funeral service companies — the same diamond-point technique is used for personalized stone gifts like engraved coasters and trays, landscaping elements, and decorative wall panels in marble, granite, and glass.

Investment and Support

MPrint prices the Master Stone at €5,000 before tax, with the package including the machine, a spare bearing, power and USB cables, a diamond needle, engraving software, a manual, and manufacturer-provided setup assistance and training. As with any impact-engraving equipment, standard workshop safety practices apply — eye protection, hearing protection, and ventilation to manage the stone dust generated during operation.

MPrint has built its business over more than 17 years supplying engraving and printing equipment, and offers support through WhatsApp, Messenger, phone, and email.
