Several dark green crystals can be observed in this emerald. Analysis with micro Raman identified them as tremolite (amphibole).

Several solid inclusions can be observed in this emerald. When viewed in reflected light where cut through, we can see that their luster is just slightly different from that of the host emerald. Analysis with micro Raman revealed that these crystals are tremolite (amphibole).

This blocky, transparent crystal stood out in its Zambian emerald host. Analysis with micro Raman revealed that it is fluorophlogopite.

This emerald from Zambia contained a small crystal of phlogopite mica, as confirmed by micro Raman. Phlogopite is a common guest in Zambian emeralds, which originate from a mica schist.

Zambian emerald inclusions may include mineral crystals, fluid inclusions, multiphase inclusions, healed fissures, growth features and other internal features formed during or after crystal growth. Such features are important to gemologists because they can provide evidence useful in identifying emerald and evaluating a possible Zambian origin.

Zambian Emerald Inclusion Photomicrographs

The Hyperion Zambian emerald gallery includes microscopic features documented in emeralds from Zambia. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.

What Inclusions Can Reveal About Zambian Emerald

Inclusions are an important part of geographic origin determination in emerald. Their form, composition and associations can provide evidence that, when considered together with other gemological properties, may support or contradict a Zambian origin.

Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Zambian emeralds.
