Certified 126.25ct Natural Aquamarine Crystal with Feldspar Matrix – Pakistan Blue Beryl Specimen

GLverify.com Certificate No: 901206543210

Certified Value: US $85.00

This Specimen is a 126.25-carat natural aquamarine (blue beryl) crystal from northern Pakistan, showing a well-defined prismatic habit with pale blue color, natural etching, and partial pegmatite matrix attached. Its surface features and mineral inclusions confirm true pocket origin, making it a desirable natural crystal specimen for collectors, educational use, or display. The consistent coloration, length, and mass of the aquamarine give it a substantial presence in hand.

1. Identified Minerals
✔ Aquamarine (Blue Beryl) — Primary Mineral
This Specimen is predominantly aquamarine.

Diagnostic features visible in the images:
Pale to medium icy-blue coloration
Hexagonal prismatic structure
Vertical striations typical of beryl growth
Natural surface etching and dissolution textures
Translucent interior with minor internal inclusions
Blocky termination and broken base indicating extraction from pegmatite matrix
The color saturation is moderate, consistent with mid-grade Pakistani aquamarine.

✔ Feldspar (Likely Albite or Microcline) — Secondary Mineral
The beige to whitish patches adhering to the crystal surface represent feldspar matrix material.

Typical identification clues:
Cream-colored, earthy appearance
Non-glassy, granular texture
Common pegmatite host mineral
Seen attached chiefly along one side of the aquamarine
Feldspar matrix is typical for aquamarine extracted from Pakistani pegmatite zones.

✔ Possible Quartz (Minor)
Some lighter patches may include small amounts of fine quartz.

Indicators:
Slight translucency
Crystalline grains in matrix areas
Quartz frequently accompanies feldspar and beryl in pegmatites.

2. Structural Description
Crystal Habit
Thick, prismatic aquamarine crystal
Good structural definition without heavy chipping
One end appears naturally formed or lightly etched
Opposite end shows a fractured base (normal for pocket extraction)

Surface Features
Noticeable etching lines and dissolution marks along the prism
Beryl striations visible on vertical crystal faces
Feldspar/matrix adhered irregularly to one side

Color & Clarity
Pale ice-blue color throughout
Semi-translucent interior
Minimal iron staining

Aesthetic Qualities
Solid form with good hand-specimen weight
Attractive natural textures
Balanced contrast between blue aquamarine and beige feldspar
This Specimen is visually appealing as a natural mineral piece rather than a gem-quality crystal.

3. Geological Context
Likely Origin:
Shigar Valley or Skardu District, Gilgit-Baltistan, Pakistan
This region is world-renowned for:
Aquamarine
Tourmaline
Topaz
Feldspar-quartz pegmatites

Formation Environment
Aquamarine forms in beryllium-rich granitic pegmatites, where:
Feldspar and quartz crystallize early, forming host matrix.
Late-stage Be-rich fluids deposit aquamarine in fractures and cavities.
Slow cooling enables formation of large prismatic beryl crystals.
Fluids produce etching, dissolving outer crystal layers and generating matte textures.
This Specimen displays all hallmarks of pegmatite-grown aquamarine with matrix remnants.

Condition & Authenticity Assessment
100% natural aquamarine
Unheated and untreated
No dyeing, coating, or stabilization
Retains original growth surfaces and internal crystal features

Suitable for:
Mineral specimen collections
