Where Every Stone Begins

Origin &
Certification

MEG sources exclusively from two of the most mineralogically significant regions on earth. Here is exactly where, how, and why.

The Two Origins

Two countries. Zero compromises.

MEG's entire inventory comes from direct partnerships with family-run operations in Artigas, Uruguay and Minas Gerais, Brazil. These are individually documented, photographed at source, and assigned a certificate before export.

Artigas, Uruguay

Artigas is the amethyst capital of the world. The basalt geology of northwestern Uruguay produces approximately 90% of the world's finest amethyst. Volcanic cavities formed 130 million years ago during the Paraná flood basalt event create the deep purple saturation and crystal clarity that defines premium-grade amethyst.

MEG sources directly from small, multi-generational mining operations in this region — family businesses with decades of knowledge of specific veins, extraction seasons, and quality grading.

Each Uruguay stone carries a certificate referencing the specific mine lot, extraction date, weight, and dimensions.

Minas Gerais, Brazil

Minas Gerais — literally "General Mines" — is one of the most mineralogically diverse states on earth. The region produces exceptional citrine, smoky quartz, tourmaline, and rare crystal formations not found at comparable quality elsewhere.

MEG's Brazilian partnerships focus on raw crystal points, clusters, and select formation specimens. The pegmatite geology produces crystals with unusually high clarity and complex internal structure.

How Certification Works

From extraction
to your hands.

1
Extraction & photography
Each stone is photographed at the mine immediately after extraction, establishing a documented visual record before any cleaning or processing.
2
Weighing & dimensioning
Weight in grams and dimensions in centimetres are recorded and added to the certificate attached to every MEG listing.
3
Certificate assignment
A unique certificate number (MEG-UY or MEG-BR prefix) is assigned before the stone leaves the source country. This prints and ships with every order.
4
Direct export to Jakarta
Stones travel directly from mine to MEG — no trading intermediaries, no repackaging. The provenance chain is unbroken.

Why It Matters

The problem with most crystals on the market

A significant proportion of crystals sold globally — including in Indonesia — are dyed, heat-treated, resin-coated, or synthetic, sold as natural specimens. Even among genuinely natural stones, origin labelling is often approximate: "South American amethyst" can mean anything from premium Artigas material to lower-grade deposits from four different countries.

MEG does not deal in approximations. Every stone has a specific origin, a specific certificate, and a specific photograph. You are not buying "a type of amethyst" — you are buying a documented physical object with a known geological history.
