Hyaline quartz point with a druzy growth base — 44×22×16 mm, 22 g, Brazil. Microcrystals of secondary quartz form a rough crust at the base of the main crystal, creating a textural transition between the smooth body and the rough base. A unique collector's piece or large format pendant.

This specific point
The main body of the crystal is of high clarity — water clear with a small internal cloud in the transition zone with the druzy base. This cloud is the visible trace of the boundary between the initial growth of the crystal and the secondary phase of microcrystal formation at the base.
The druzy base shows a uniform distribution of quartz microcrystals clearly differentiated from the smooth body of the crystal.
How druzy growth forms at the base
When a growing quartz crystal is partially exposed to the circulation of hydrothermal fluids at its base — for example, if the matrix to which it is attached dissolves or cracks — a secondary phase of crystallization can begin on the exposed surface. New microcrystals grow on the body of the main crystal, forming the characteristic druzy crust, without interrupting the growth of the parent crystal.
In this point, the transition between the hyaline body and the druzy base is gradual: there is an internal cloud zone that marks the moment when the growth regime changed, before the formation of the surface microcrystals. It is a "geological biography" in a single crystal.
What this point is good for
-
Mineral collection — Two growth features in a single crystal (hyaline point + druzy base) documenting distinct phases of the same hydrothermal process.
-
Large format wire wrap pendant — The 44 mm length allows for wire wrapping with silver or copper wire, leaving both the termination and the druzy base visible.
-
Open bezel setting — A bezel that covers part of the base protects the more fragile druzy area while exposing the termination.
-
Self-supporting decoration — The flat base of the druzy area allows the point to stand on its own on a shelf or altar.
The quartz point in lapidary tradition
Quartz points are one of the most collected formats in the history of jewelry and lapidary. Brazilian quartz points have been exported since the mid-19th century from the states of Minas Gerais and Goiás, which contain the most productive deposits in the world.
In crystal tradition, hyaline quartz (clarity and amplification of intention) is the quintessential base stone. Points are commonly used in meditation and as tools in crystal practice.
Symbolic associations belong to cultural traditions. They are shared for educational purposes, not as medical advice.
How to recognize genuine hyaline quartz
The Mohs hardness of 7 for quartz is the first indicator: it is not scratched by a steel coin (Mohs 5.5-6). Genuine quartz also feels colder to the touch than glass, due to its higher thermal conductivity. Natural terminations show edges with slight irregularities under magnification.
Frequently Asked Questions
Is the surface polished or natural?
The point and the faces of the prism are natural growth or fracture surfaces, not mechanically polished. The druzy base is equally natural. There is no artificial polishing on any area of the crystal.
Is it heat-treated or irradiated?
No detectable treatment. Hyaline quartz does not need treatment for its natural color (colorless). Smoky quartz and citrine are often heat-treated, but transparent quartz is valued in its natural state.
Is the druzy area of the base fragile?
Druzy microcrystals have a Mohs hardness of 7 but are small and can chip off with direct impacts. Handle the base area with care, especially during jewelry mounting.
