Tumbled strawberry quartz —macrocrystalline quartz with hematite and goethite inclusions that stain the matrix from deep red to raspberry— in size 3-4 × 2-3 cm. The name "strawberry quartz" is commercial and describes the reddish color with dark spots and veins reminiscent of the fruit's surface. Origin: Brazil and Madagascar.
Material Data Sheet

Macrocrystalline quartz (SiO₂) with hematite and goethite inclusions (commercial name: strawberry quartz) |
| Color |
Vivid red to raspberry red with dark hematite spots and veins; saturation variations per piece |
| Size |
3-4 × 2-3 cm (natural variations within the batch) |
| Shape |
Tumbled; rounded outline |
| Finish |
Smooth polish with a slight natural quartz luster |
| Hardness |
7 Mohs (matrix quartz) — one of the most scratch-resistant tumbled stones for daily use |
| Origin |
Brazil (more saturated variety) and Madagascar (with possible green epidote inclusions) |
| Treatment |
Untreated. The red color comes from native iron oxide inclusions (hematite, goethite) in the quartz matrix |
| Piece type |
Unique inclusion distribution per tumbled stone; selection by batch |
How the red color forms
Strawberry quartz is macrocrystalline quartz in whose formation hematite (Fe₂O₃) and goethite (FeO·OH) particles —two iron oxides— were incorporated, trapped in the crystal lattice or deposited in internal microfractures. Hematite contributes intense red and crimson tones; goethite adds brown and golden nuances in transition zones. The result is a translucent stone in pure areas and opaque red where the oxide is concentrated. In Madagascar deposits, strawberry quartz frequently coexists with epidote, which may appear as green spots within the red; in Brazil, the background tends to be more uniformly pinkish.
What this format is good for
-
Wire wrap — 7 Mohs hardness, the highest among common quartz types; withstands medium and thick gauges (0.8-1.5 mm) without risk of marking the surface; the 3-4 cm size offers space for elaborate pendant compositions
-
Macrame — medium weight and rounded outline are easily tied without a cap; intense red stands out against white, beige, or black thread
-
Pocket stone — high hardness makes strawberry quartz one of the most resistant tumbled stones to daily use; withstands everyday friction against keys and surfaces without micro-scratches
-
Collection of iron oxides in quartz — the unusual color among quartz varieties makes it stand out in collections of red minerals alongside carnelian, red jasper, and unfaceted ruby
Strawberry quartz in cultural tradition
Quartz with iron oxide inclusions has been worked since ancient times under different names depending on color saturation and transparency: carnelian (orange-red translucent, microcrystalline quartz), red jasper (opaque), and red smoky quartz (with partial transparency). The name "strawberry quartz" became popular in the gem market in the 1980s to describe macrocrystalline quartz with intense reddish-raspberry hematite, distinguishing it from the more orangey carnelian. In modern crystal healing readings, it is associated with vitality and solar energy, extending the symbolic associations of the color red with dynamism and action that appear in multiple cultural traditions.
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 strawberry quartz
Authentic strawberry quartz shows variations in color saturation and distribution: more translucent areas and redder areas, with irregular hematite spots and veins. Under a 10× loupe, inclusions appear as internal particles, not as a surface dye. Dyed quartz shows dye concentration in microfractures (well-defined dark edges) and a uniformly colored external surface. Irradiated quartz tends to a more uniform and saturated red than natural. 7 Mohs hardness is a practical sign: genuine quartz is not scratched by a steel blade (5-6 Mohs); red glass or resin is.
Frequently Asked Questions
Is it the same as carnelian?
No. Carnelian is a variety of chalcedony (microcrystalline quartz, homogeneous milky texture) with orange-red hematite inclusions and high translucency. Strawberry quartz is macrocrystalline quartz (crystalline, not micro) with intense red hematite concentrations visible as distinguishable spots and veins. The visual appearance is distinct: carnelian looks like wax; strawberry quartz, like red glass with internal spots.
Is it durable for everyday jewelry?
Its 7 Mohs hardness makes it suitable for wire-wrapped or macrame pendants, earrings, and bracelets. For very intense use rings, the polished surface may slowly lose luster due to accumulated friction; unmounted tumbled stones are more suitable for pieces of moderate exposure.
Are the dark spots and marks flaws?
No. They are the concentrations of hematite or goethite that define the visual character of the mineral. A uniformly red piece without internal variations would be a sign of treatment or imitation.
How much does each tumbled stone weigh approximately?
In the 3-4 × 2-3 cm range, the usual weight is between 15 and 35 grams depending on thickness and local density (pure quartz: 2.65 g/cm³; areas with hematite: up to 5.26 g/cm³, denser). Weight variability reflects the natural composition of each piece.
How to care for it?
Clean with a soft cloth dampened with water. Its 7 Mohs hardness makes it scratch-resistant in normal use. Avoid sudden shocks that could fracture the crystal. More in the jewelry care guide.
