Smoky quartz in round brilliant cut, in various diameters — see variant. The round brilliant cut with a triangular-faceted crown and conical pavilion maximizes the refraction of the smoky color, transforming brown and gray tones into flashes ranging from bronze to champagne. For setting in fine jewelry in sterling silver.

This specific gemstone
The smoky color of quartz comes from natural irradiation during formation: geological radiation displaces structures in the crystal lattice that absorb specific wavelengths of visible light. In brilliant cut, this selective absorption mechanism produces a visual depth effect — the gem appears to have more color in the center than at the edges, which adds dimensionality to the finished piece.
The calibrated round geometry allows for direct mounting in standard setting cups. Suitable for solitaires, sets, and modern geometric designs.
What settings it works for
-
Round bezel setting (sterling silver) — The calibrated diameter fits standard bezel mounts without adjustment; we recommend closed bezel for this geometry.
-
Prong setting (4 or 6 prongs) — Shows more light in the gem; ideal for solitaire pendants and statement rings.
-
Wire wrap — The round format lends itself to spiral wrapping; smoky quartz contrasts well with the warm tone of copper.
Smoky quartz in lapidary tradition
Smoky quartz was worked by the Romans to reduce sun glare before optical glass existed. In Scotland, "cairngorm" (a dark smoky quartz variety) was the national mineral for centuries and remains the traditional ornament of the Highland kilt. In crystal tradition, smoky quartz is associated with grounding, protection, and clarity in stressful contexts.
The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice.
How to recognize genuine smoky quartz
Genuine smoky quartz has color distributed gradually or with concentrations in growth zones visible under magnification. Smoky glass has perfectly uniform color and is not cold to the touch like quartz. Artificially irradiated smoky quartz usually has a very intense and uniform color, different from natural gradation.
Frequently asked questions
Is it natural or artificially irradiated?
No detectable treatment. The smoky color is natural; the statement is based on gemological observation, without formal certification included.
Is it calibrated?
Yes, calibrated to ±0.1 mm — suitable for mounts of the corresponding diameter without adjustment. Verify the exact diameter in the selected variant.
Is it suitable for a ring?
Yes — with 7 Mohs, it is resistant to daily wear in a ring. Avoid direct impacts on the facet edges.
Can it be used in ultrasonic cleaners?
Not recommended if the gem has visible inclusions. For clean quartz, ultrasound is generally safe; consult with the setter.
How is it cared for?
Warm water and mild soap; dry immediately. See care guide.
