Trillion-cut citrine available in 7 and 8 mm. The equilateral triangle with 43 facets maximizes the refraction of the golden-yellow citrine quartz, generating a brilliance intensity superior to round brilliant cuts for gems of this size. For setting in fine jewelry in 925 silver.

This specific gem
The trillion cut in citrine is a deliberate technical choice: the triangle amplifies light dispersion better than a round cut in 7-8 mm gems, because the long, angled facets create more visible refraction points. Natural citrine — unlike heat-treated— has a soft yellow with slight internal variations that add visual depth instead of a flat color.
The calibration allows direct mounting in standard trillion settings without adjustment. Suitable for prong, bezel, and three-point settings.
What type of mounting it works for
-
Three-prong setting (925 silver) — The trillion cut is native to a three-prong setting at the vertices; it is the most visible and efficient combination for this geometry.
-
Triangular bezel setting — For those who prefer more gem protection, the triangular bezel is a valid alternative with a more contemporary finish.
-
Pendants and statement rings — The trillion takes visual prominence in minimalist pieces where the gem is the sole design element.
Citrine in lapidary tradition
Genuine citrine is less common on the market than it seems: most commercial "citrine" is heat-treated amethyst or smoky quartz. The natural yellow color comes from trace amounts of iron in the crystal lattice. It was called "merchant's stone" in 19th-century Europe due to its resemblance to topaz. In crystal tradition, citrine is associated with abundance, mental clarity, and solar energy.
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 citrine
Natural citrine has a soft yellow with possible internal tone variations. Heat-treated citrine has a very uniform intense orange and is visually cleaner. Citrine quartz is cold to the initial touch like all quartz and may show micro-inclusions under magnification.
Frequently asked questions
Is it natural or treated citrine?
No detectable treatment. The golden-yellow is natural; the declaration is based on gemological observation, without formal certification included.
Is it calibrated? Does it fit standard settings?
Yes, with a tolerance of ±0.1 mm — suitable for standard 7mm and 8mm trillion jewelry settings, without additional adjustment.
What type of setting is best?
Three prongs at the vertices is the most common for trillion. A triangular bezel offers more protection. Both are viable in 925 silver.
Can I use it in a ring?
Yes — with 7 Mohs, it is suitable for a ring with daily wear. We recommend protecting the three vertices of the trillion, which are the most vulnerable points to impact.
How is it cared for?
Lukewarm water and neutral soap; avoid ultrasound if the gem has inclusions. See care guide.
