Every crystal holds a light. But sometimes that light is hidden beneath encrustations, oxidation, or secondary coatings. Mechanical cleaning is often the firstβand decisiveβstep to recover the crystal's original geometry and beauty.
At MCP, we use precision tools and techniques tailored to the nature of the matrix and the dominant crystal. The goal is never to remove "too much," but to selectively eliminate what prevents visual and mineralogical reading.
Micro-sandblasters, micro-burrs, precision needles, and optical supports allow us to work delicately, even on the most fragile zones. Each intervention is preceded by a study phase to anticipate results and agree with the client on the best strategy.
π Wondering if your specimen would benefit from mechanical cleaning? Share a few details: weβll evaluate its potential together.

Every specimen tells a story, but not all stories are legible at first glance. When the host rock conceals the crystal's geometry or balance, we apply a technique of precision: trimming.
Cutting, reducing, lightening: the goal is never to alter the nature of the specimen, but to reveal its beauty. In the lab, we define the ideal volume to highlight the crystal habit, mineral arrangement, and three-dimensionality.
Sometimes trimming is done to meet size criteria (thumbnail, miniature, small cabinetβ¦), other times to retrieve secondary pieces from complex specimens. Each decision is preceded by visual analysis, often supported by photographic renderings.
Because it's not just about cutting: it's about choosing where the essence should emerge.
π Want to know if your specimen could benefit from trimming? Send us a few images: weβll assess it together.

π In MCP every crystal is a work of art.
For years, weβve been telling the story of minerals. Today, we open a window onto the heart of our work: laboratory services.
From matrix reduction to mechanical and chemical cleaning, from aesthetic restoration to conservative reconstruction, and from museum preparation to direct acquisition at mining sites β each phase showcases a unique expertise developed with precision, passion, and method.
Founded in 2012 by Federico Pezzotta, MCP is now the best worldβs leading lab for mineral specimen preparation. Our goal is constant: to enhance the crystalβs aesthetics, integrity, and readability while respecting its original structure.
Our approach is multidisciplinary, blending scientific, technical, and artistic skills. With over 600 international clientsβcollectors, dealers, museums, and mining companiesβwe have treated tens of thousands of specimens, helping set new standards in mineral preparation.
If you own a specimen and wonder how it could be improved, share its story and a few photos with us: our team can offer tailored advice, based on technical analysis and experience built over thousands of case studies.

Topaz β Crystallography and natural purity
Mineralogically, topaz is an aluminum fluorosilicate with an orthorhombic crystal system. This specimen is a textbook example: sharp faces, intact terminations, and fine striations across some surfaces all testify to its orderly growth in pegmatitic environments.
The crystalβs high transparency and lack of visible inclusions are key quality criteria in mineralogical classification. Moreover, the presence of golden mica reinforces the paragenetic diagnosis, signaling the evolution of a hydrothermal system enriched with rare elements.
This specimen, complete and unrestored, stands as a visual and crystallographic reference for topazes from Teixerinha.

Topaz β An ancient name for a modern gem
The name βtopazβ has ancient and fascinating origins: it may derive from the island of Topazos in the Red Sea, or from the Sanskrit word βtapas,β meaning fire. Although known for millennia, the sky-blue topaz from Teixerinha only began gaining prominence on the market in recent decades, becoming a symbol of modern Brazilian mineralogy.
This transparent, crystalline specimen represents a new vision of topaz: not merely a gemstone for cutting, but a collectible object to study and admire in its natural form. Mounted on a plexiglass base without any restoration, it bridges the gap between historical legacy and contemporary appreciation.
