Included Quartz refers to Quartz crystals that contain other minerals trapped within them during growth. These inclusions may appear as needles, clouds, veils, phantoms, sprays, plates, threads, or granular deposits, each reflecting the geological conditions present at the time of formation.
Common inclusions include Chlorite, Rutile, Tourmaline, Titanium-bearing minerals, Iron oxides, and many others. Each specimen is inherently unique, as the timing, chemistry, and environment of growth determine the inclusion’s shape, placement, and density.
Included Quartz occurs worldwide, with notable localities in Brazil, Madagascar, Pakistan, India, the United States, and parts of Africa. Because inclusions record a snapshot of the crystal’s growth history, many collectors consider Included Quartz to be a visual and geological record of Earth’s evolving conditions.
Included Quartz is composed of silicon dioxide (SiO₂) and crystallizes in the trigonal crystal system, consistent with all Quartz varieties. The defining feature is the presence of one or more foreign minerals incorporated during crystal growth.
Inclusions form when Quartz grows in environments where other minerals are suspended in hydrothermal fluids. As the Quartz crystal develops, these minerals may become trapped internally rather than being excluded or deposited on the surface. Growth may continue around the inclusion, fully enclosing it within the crystal body.
In some cases, inclusions outline earlier growth stages, forming phantoms. In others, needle-like or fibrous inclusions such as Rutile or Tourmaline grow simultaneously with the Quartz, creating complex internal structures.
| Property | Value |
|---|---|
| Mineral Species | Quartz with mineral inclusions |
| Chemical Formula | SiO₂ (host crystal) |
| Crystal System | Trigonal |
| Hardness (Mohs Scale) | 7 (host crystal) |
| Luster | Vitreous |
| Transparency | Transparent to translucent |
| Defining Feature | Internal mineral inclusions |
From a geological perspective, inclusions provide valuable insight into the temperature, pressure, and chemistry present during crystal formation. Each Included Quartz specimen is effectively a natural archive of its growth environment.
⚠️ Handling:
Included Quartz is generally durable, but internal fractures or delicate inclusions may be present. Handle gently and avoid sudden impacts.
🧼 Cleaning:
Water-safe for brief rinsing. Avoid prolonged soaking, especially for crystals with visible fractures or porous inclusions. Dry thoroughly.
☀️ Light:
Most Included Quartz is light-stable. Some iron-rich inclusions may darken slightly with prolonged intense sunlight.
📦 Storage & Display:
Store separated from harder specimens to prevent chipping. Display securely to protect terminations.

Double Terminated Quartz refers to Quartz crystals that naturally form with a termination at both ends, rather than the more common single-point growth where one end is attached to a matrix or host rock. This is a true growth habit, not a separate mineral species, and it can occur in clear quartz, smoky quartz, amethyst, and included varieties depending on locality and conditions.
Double termination typically forms when a Quartz crystal grows in an open cavity where both ends remain free, or when the crystal grows in a fluid or clay-rich environment that allows it to develop without permanently attaching to a host surface. Because this requires specific stability and space during growth, fine double terminated specimens are less common than standard points.
Some double terminated crystals are true “floaters,” meaning they grew completely free and may show overall symmetry, clear faces, and terminations at both ends. Others may have one end slightly more developed, or show subtle contact points where the crystal briefly touched surrounding material during growth.
In the marketplace, it is important to distinguish natural double termination from cut or polished pieces. Authentic double terminated Quartz shows natural growth lines, consistent termination geometry, and unpolished faces (unless the specimen has been intentionally polished as a separate treatment, which should be disclosed).
Double Terminated Quartz is composed of silicon dioxide (SiO₂) and crystallizes in the trigonal crystal system, like all Quartz. The double terminated form is created by growth conditions rather than chemistry.
This habit most commonly develops in:
Because Quartz is durable and chemically stable, double terminated crystals often preserve their terminations well—though tips can still chip if struck.
| Property | Value |
|---|---|
| Mineral Species | Quartz (Double Terminated growth habit) |
| Chemical Formula | SiO₂ |
| Crystal System | Trigonal |
| Hardness (Mohs Scale) | 7 |
| Luster | Vitreous |
| Transparency | Transparent to translucent |
| Fracture | Conchoidal |
| Defining Feature | Natural terminations on both ends |
From a formation perspective, the key difference is that energy of growth and crystallographic development occurred in two directions. This often creates a strong sense of symmetry and “completeness,” which is one reason these crystals are treasured both aesthetically and in metaphysical practice.
⚠️ Handling:
Double Terminated Quartz has two vulnerable ends. Always lift from the center or base area and avoid tapping either termination against hard surfaces.
🧼 Cleaning:
Water-safe for brief rinsing. Avoid prolonged soaking if the crystal contains fractures or inclusions. Dry thoroughly.
☀️ Light:
Clear Double Terminated Quartz is light-stable. Colored varieties (smoky/amethyst) should be protected from prolonged intense sunlight.
📦 Storage & Display:
Store cushioned and separated from other specimens to protect both tips. For display, use stable stands that support the center without pressure on terminations.
