Transparent hyaline quartz cabochons with phantom hematite inclusions, available in two formats: oval (12 × 6 × 3 mm) and teardrop (16 × 6 × 3 mm). The hematite formations create internal figures — "phantoms" — that float in the crystal like layers of previous growth suspended in time. Hand-cut in our lapidary workshop.

This specific piece
The hematite inclusions in these cabochons form internal silhouettes reminiscent of a previous crystal enclosed within the current crystal: hence the name "phantom." The hematite layers were deposited during a pause in the quartz's growth, when the iron mineral precipitated onto the surface of the developing crystal. When the quartz resumed its growth, it enveloped these layers, preserving their shape. The visual result is a reddish-silver three-dimensional object suspended within a completely transparent matrix.
The ultra-thin profile format (3 mm) was the central lapidary decision: it maximizes the transparency of the quartz and allows the internal formations to be seen without obstruction. This profile also facilitates very low relief settings — ideal for flat earrings or minimalist pendants.
How a phantom quartz is formed
Phantom quartz is formed when the growth of a quartz crystal is interrupted for a geological period, and during that interval, another mineral precipitates on its surface. When conditions become favorable for quartz again, the crystal grows anew, covering the layer of the interposed mineral. In the case of phantom hematite, the iron mineral that precipitated during the pause was hematite. The "phantom" shape reproduces the silhouette of the quartz crystal at the moment of interruption: usually pyramidal in crystals of normal habit. This geological sequence can repeat several times, generating multiple superimposed "phantoms" in the same crystal.
For what setting it works
-
Pendants and earrings with bezel setting (925 silver) — The 3 mm profile and compact dimensions (12 and 16 mm) are ideal for everyday jewelry in an elegant format. The transparency of the quartz with the reddish internal formations is best appreciated when the piece receives light from behind.
-
Minimalist rings with low bezel — The ultra-flat profile allows for a very low wall bezel. For everyday ring wear: a closed bezel that protects the edge.
-
Fine wire wrap — With 24-26 gauge silver, the wrap can go around the perimeter without hiding the internal formations of the stone.
Phantom hematite in lapidary tradition
Phantom quartz is known in international trade as "phantom quartz" or "ghost crystal." Its appreciation in lapidary and collecting dates back to the 19th century when European naturalists began documenting the mechanisms of episodic crystal growth. The first scientific descriptions of phantom quartz came from Alpine deposits, where high-purity quartz crystals showed inclusions of green chlorite and hematite as visible crystalline stratigraphy.
In crystal tradition, quartz with phantom hematite is associated with the memory of transformations: each visible layer inside is a record of a real geological change, a pause, and a resumption. It is interpreted as a reference to the ability to integrate one's own changes without losing essential form.
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 phantom quartz
Genuine phantom quartz has inclusions clearly inside the crystal, not on the surface or in fractures. When rotating the piece, the internal "figure" remains in its position in space — it does not move with the surface. Under magnification: the inclusion has a shape reminiscent of a pyramid or crystal silhouette. Imitations by painting the base or artificial inclusion of pigments show irregularities at the edges of the "phantom" and absence of the characteristic three-dimensional depth.
Frequently Asked Questions
What exactly is "phantom hematite"?
These are layers of hematite (iron mineral) that were deposited on the quartz during a pause in its growth. When the quartz resumed growth, it enveloped these layers. The "phantom" is the silhouette these layers form within the transparent crystal, recalling the shape of the crystal at the time of interruption.
Is the material treated?
No detectable treatment. The internal formations are natural mineral hematite. Statement based on lapidary observation; no formal gemological certification.
Is the 3 mm profile strong enough?
Quartz with 7 Mohs maintains its structural integrity in 3 mm profiles for jewelry use. For ring settings, we recommend a bezel that completely surrounds the perimeter; for pendants and earrings, the profile poses no additional risk.
What is the difference between oval and teardrop?
They are two individual pieces with the same mineral characteristics but different shapes and sizes: the oval measures 12 × 6 mm and the teardrop 16 × 6 mm. Each has its own unique internal phantom hematite pattern.
Are the dimensions exact?
With a tolerance of ±0.5 mm. Hand-cut, not industrially calibrated.
How to care for it?
Clean with warm water and a soft brush. Dry immediately. Store separately from abrasive materials. More information in our jewelry care guide.
