This specific piece
The amethyst in this lot presents a medium-high saturation purple, homogeneous across the crown. The heart cut multiplies the internal brilliance in the central area of the piece, while the two upper lobes create a V-shaped flash when viewed from above — a characteristic optical effect of well-executed heart-cut quartz gems.
Why amethyst is purple
Pure quartz is colorless. Amethyst owes its purple color to the presence of trace amounts of iron (Fe³⁺) in the crystal lattice, which selectively absorb yellow-green wavelengths and allow purple-violet to pass through. The color forms during crystal growth under conditions of natural irradiation (gamma rays from radioactive elements in the host rock). This is why it is stable in everyday use but can fade with prolonged and intense sun exposure; jewelry-grade amethyst should not be continuously exposed to direct UV for months.
What setting it works for
-
925 silver stud setting (stud earring) — the 6 mm heart shape is one of the most popular for stud earrings, providing an elegant and versatile option for daily wear.

Amethyst in jewelry tradition
Amethyst is one of the quartz gems with the longest jewelry history. In ancient Greece and Rome, an amethyst cup or a ring with this stone was considered protection against intoxication (the name comes from the Greek amethystos, "not drunk"). The Catholic Church adopted it as an episcopal symbol: the bishop's ring has often been amethyst since the Middle Ages. In Victorian jewelry, it was the preferred gem for "half-mourning," when pure black gave way to violet tones. In crystal tradition, amethyst is associated with wisdom, calm, and clear thinking — the stone for balancing emotion and reason.
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 amethyst
Genuine amethyst has a hardness of 7 Mohs: it cannot be scratched by a steel knife. Purple glass or purple cubic zirconia are frequent substitutes; glass is soft (5.5 Mohs) and completely homogeneous under magnification, while amethyst can show growth veils or small inclusions. The color of genuine amethyst can vary in areas of the crystal (color zoning), something that dyed glass does not exhibit. Amethyst is also birefringent (RI 1.54–1.55), which can be checked with a refractometer.
Frequently Asked Questions
Is it genuine amethyst quartz?
Yes. It is genuine quartz with natural purple color, without heat treatment. Its hardness of 7 Mohs distinguishes it from imitation purple glass.
Does it have any treatment that affects the color?
No. The purple color of amethyst is completely natural, a result of the presence of iron in the crystal lattice. It does not require heat treatment (unlike citrine).
Are all 6 mm pieces identical and suitable for paired earrings?
The units are selected for the same calibrated size (6 mm) and are practically interchangeable for mounting in earring pairs.
