Certified 79.65ct Natural Aquamarine Crystal with Mica – Premium Pakistan Blue Beryl Specimen

GLverify.com Certificate No: 901148540265

Certified Value: US $130.00

This Specimen is a 79.65-carat natural aquamarine (blue beryl) crystal from the world-renowned pegmatite fields of northern Pakistan. It displays a robust, well-defined prismatic form with partial natural termination faces and internal clarity characteristic of high-quality aquamarine. Minor inclusions of mica and subtle iron-oxide staining contribute to its geological authenticity. With its attractive size, clean geometry, pale blue tint, and localized mica attachment, this specimen represents a classic example of Pakistan’s elite aquamarine production and is suitable for display, study, or collection.

1. Identified Minerals

✔ Aquamarine (Blue Beryl) – Primary Mineral
This is the dominant mineral in This Specimen.

Diagnostic visual features:
Pale icy-blue coloration
Transparent to translucent interior
Strong hexagonal prism geometry
Flat to uneven natural termination faces
Conchoidal fracture surfaces where naturally broken
Vitreous (glassy) luster

This is a textbook example of aquamarine from Pakistan pegmatites.

✔ Mica Group Mineral (Muscovite or Phlogopite)
A small but distinct mica cluster is attached along the side of the aquamarine crystal.

Visible characteristics:
Silvery-tan to bronze flake appearance
Thin, flexible laminae with perfect basal cleavage
Pearly sheen
Classic accessory mineral in aquamarine pockets
Color suggests a muscovite–phlogopite intermediate.

✔ Iron-Oxide Staining (Secondary Mineralization)
The yellowish internal and surface areas are consistent with:
Goethite or limonite residues
Typical of natural aquamarine cavities exposed to oxidizing fluids
This does not detract from value—collectors often appreciate natural pocket staining.

2. Structural Description of This Specimen
Aquamarine Crystal Habit
Medium-sized thick prismatic crystal
Well-developed hexagonal form
Partial natural terminations visible at multiple edges
Clean faces showing minimal etching
Good internal transparency with minor inclusions
This Specimen stands out because it is almost entirely a single aquamarine crystal rather than a matrix-heavy cluster.

Mica Attachment
A small mica “rosette” attached at one side
Indicates the aquamarine grew in a mica-rich pegmatite cavity
Adds mineralogical context and display charm

Overall Aesthetic Qualities
Bright pale-blue color visible even outdoors
Excellent hand-specimen size
Natural growth features preserved
Attractive combination of clarity + inclusions
Very good collector, display, or metaphysical piece

3. Geological Context
Likely Origin:
Shigar Valley, Skardu District, Gilgit-Baltistan, Pakistan
This region is globally famous for producing:
High-clarity aquamarine
Elbaite tourmaline
Muscovite and other pegmatite-associated minerals

Formation Environment:
Aquamarine forms in granitic pegmatites where the following occurs:
Slow cooling of Be-rich granitic melt allows beryl (aquamarine) to crystallize.
Mica minerals form early, lining the pegmatite cavity walls.
Hydrothermal fluids enrich the beryl with Fe²⁺, creating aquamarine’s blue coloration.
Iron-oxide staining develops during later oxidation stages.
This Specimen reflects all these classic pegmatitic growth features.
