Certified 85.45ct Natural Aquamarine Crystal – Gem-Grade Blue Beryl from Pakistan

GLverify.com Certificate No: 901166054951

Certified Value: US $210.00

This Specimen is an 85.45-carat natural aquamarine (blue beryl) crystal from the high-altitude pegmatite fields of northern Pakistan. It displays a long, well-defined prismatic form with distinct hexagonal geometry, soft sky-blue coloration, excellent translucency, and classic parallel growth striations. Minor internal inclusions and small attached mineral remnants emphasize its natural origin. This is a highly aesthetic, jewelry-grade aquamarine crystal suitable for collectors, lapidaries, or display.

1. Identified Minerals
✔ Aquamarine (Blue Beryl) — Primary Mineral
This Specimen is overwhelmingly a single, large aquamarine crystal.

Visible diagnostic features:
Pale to medium icy-blue coloration typical of Pakistani aquamarine
Strong hexagonal prismatic habit
Multiple parallel vertical striations (classic beryl growth feature)
Partial natural termination visible at the top
Translucent to semi-transparent body
Subtle internal veils and natural inclusions
The crystal clarity and symmetry indicate high-quality, collector-grade material.

✔ Minor Mica Attachment (Accessory Mineral)
Small fragments of mica appear along one side.

Characteristics:
Silvery-tan platy sheets
Pearly luster
Perfect cleavage planes
These small mica remnants confirm its pegmatitic origin but do not detract from the aquamarine’s visual appeal.

✔ Possible Feldspar or Quartz Residue (Very Minor)
A small area on one side contains whitish mineralization, likely:
Feldspar
Quartz
Pocket residue

This is common for natural crystals removed directly from pegmatite cavities.

2. Structural Description
Crystal Habit
Long, columnar aquamarine crystal
Strong, sharp edges showing minimal wear
Well-preserved prism faces with classic beryl striations
Termination is partially intact, showing natural growth and cleavage surfaces

Color & Clarity
Pale ice-blue color evenly distributed
Transparent zones toward the center
Slight internal veils from natural fluid inclusions

Surface & Form
Very clean geometry
No heavy etching
Small edge irregularities consistent with natural extraction
This is a gem-quality crystal specimen, not a cluster.

3. Geological Context
Likely Origin:
Shigar Valley or Chumar Bakhoor, Gilgit-Baltistan, Pakistan

These areas are globally known for producing:
High-clarity aquamarine
Large, well-formed beryl crystals
Associated mica and quartz pegmatite minerals

Formation & Growth Environment
Aquamarine forms in:
Granitic pegmatites enriched with beryllium
Slowly cooling pockets where fluids encourage long crystal growth
Conditions that create the textbook vertical striations seen on This Specimen
The pale blue color is produced by trace iron (Fe2+) inside the crystal lattice.
This Specimen is a classic example of long-prismatic Pakistani aquamarine.

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
Display pieces
