Lapis Lazuli 6mm Round Cabochons

6 mm round lapis lazuli cabochon with characteristic ultramarine blue color, golden pyrite flecks or veins, and a white calcite base. For delicate 925 silver settings: stud earrings, minimalist rings, and small pendants.

Piece Details

This Specific Piece

Lapis lazuli is not a mineral but a composite rock: lazurite (sodalite with sulfur, which provides the blue) coexists with calcite (white) and pyrite (metallic gold) in proportions that vary naturally between specimens. The 6 mm cabochons in this lot show a predominance of blue with a variable presence of pyrite — some pieces show a tiny metallic gold dot, others a small spot, and others have a more uniform distribution of blue with no visible pyrite.

At 6 mm in diameter, this cabochon is the smallest format suitable for stud earrings or minimalist rings. The deep blue contrasts directly with the silver color of the setting without the need for an additional element.

How Lapis Lazuli is Formed

Lapis lazuli is formed by contact metamorphism in limestones near igneous intrusions. The heat and fluids from the intrusion transform calcite into lazurite (sodalite group tectosilicate with S₃⁻ as the blue chromophore), while pyrite precipitates from solutions rich in Fe²⁺ and S.

For Which Mounting It Works

• Bezel setting (925 silver) — the 5-6 Mohs hardness makes the closed bezel the only recommended mounting for use in an active ring or earring; the bezel protects the edge from scratches and chipping.
• Stud earrings — the 6 mm round format is standard for stud earrings; a pair with a 925 silver bezel and butterfly clasp is one of the most classic designs in lapis lazuli jewelry.
• Wire wrap — an alternative for those who work with wire; for 5-6 Mohs hardness, we recommend a wrap that completely covers the edge to minimize exposure to friction.

Lapis Lazuli in Lapidary Tradition

Lapis lazuli from Badakhshan reached Egypt and Mesopotamia over 6,000 years ago, documented in late Neolithic tombs and in the funerary adornments of Tutankhamun's tomb. It was the raw material for ultramarine blue pigment — the most expensive in the medieval world, used by artists such as Vermeer and the Flemish Primitives for the Virgin Mary's garments.

The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice or a substitute for professional care.

How to Recognize Genuine Lapis Lazuli

Genuine lapis lazuli has a blue color that is not uniform but slightly mottled by the distribution of calcite and pyrite — a surface of absolutely flat and uniform color may indicate dyeing or plastic. Under magnification, genuine pyrite has a warm metallic luster (golden) and angular edges; imitations with "gold powder" have rounded particles and colder luster.

Frequently Asked Questions

Where does this lapis lazuli come from?

From Afghanistan, Badakhshan province, the main worldwide deposit of gemological lapis lazuli. The material comes from wholesale lapidary stock with origin traceability.

What mounting is it best suited for?

For a 6 mm closed bezel in 925 silver. The 5-6 Mohs hardness makes it essential to protect the edge of the stone; we recommend a closed bezel setting. The 6 mm round format is standard for stud earrings or minimalist rings.

Has it had any treatment?

Untreated. The blue is a result of natural lazurite, and the pyrite is natural. Statement based on lapidary observation; the piece does not include formal gemological certification.
