Trigonic Quartz Cluster "Lemurian Cloud" from Minas Gerais, Brazil - 652g

Trigonic quartz is also considered a type of ice crystal and is found in regions such as Brazil and the Himalayas.

Brazil is regarded as the main source, while in the Himalayas trigonic markings often appear on crystals that are otherwise known as ice crystals.

What we call trigonic quartz generally has two characteristic features:

• Downward-pointing triangular markings (trigonic patterns) appearing on the terminal facets

• An icy, melted or deeply etched crystal form typical of so-called ice crystals

I feel that these two characteristics may also be related to how trigonic quartz forms.

In record-keeper crystals, the triangular markings point upward (△).

They are sometimes interpreted as marks of crystal growth, much like plants growing upward toward the light.

Trigonic markings, by contrast, point downward (▽).

This may suggest that the crystal received some influence from above.

This influence may originate within the Earth's crust, or perhaps from something much farther away, such as cosmic radiation.

Cosmic rays are known to pass through nearly all matter and continuously reach the Earth's surface.

For that reason, it does not seem impossible that minerals deep underground may also be exposed to them.

Ice Crystal

Another feature often seen in trigonic quartz is its somewhat swollen form.

This may also be one of the characteristics associated with Ice crystals.

Ice crystals sometimes appear as incomplete forms, shaped by dissolution or by interruptions during their formation.

The softened and rounded edges often seen in trigonic quartz may suggest that the crystal itself experienced some degree of heating like Ice crystals.

It may be that the quartz became heated by some reaction, after which hydrothermal fluids or moisture etched the surface, leaving behind the swollen textures and traces of erosion that we see today.

Perhaps it is because the crystal experienced such unusual processes that trigonic quartz often carries a particularly strong sense of presence. Trigonic quartz is known for its strong healing resonance.

Recrystallized Crystal

When looking at its wrinkled and etched surface, one cannot help but feel that something significant may have happened to this stone.

After being exposed to hydrothermal activity and partially dissolved, the crystal may have begun to recrystallize — almost as if awakening and glowing white-hot from within.

It feels as though the crystal is regenerating in a way different from its normal growth process.

It is reminiscent of skin regenerating after a burn.

The strong healing resonance often associated with trigonic quartz may be a sign that the crystal endured a great trial and then recovered from it.

In that sense, trigonic quartz almost feels like a physician among crystals.
