Garnet Inclusions

Explore garnet inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural garnet, documented with information on geographic origin, treatment, lighting conditions, field of view, photographer and published references.

Needle-like inclusions and platelets form a pattern reminiscent of circuit-board traces.
A thin, orange platelet appears to float in this garnet from Mozambique. Although attempts were made to identify it with Raman spectroscopy, results were not conclusive, perhaps because the inclusion was so thin.
A small, doubly refractive anorthite crystal (identified by micro Raman) is suspended in a garnet from Mozambique.
Several transparent crystals decorate the interior of this garnet from Mozambique. Micro Raman identified the orange crystals as rutile, while the colorless transparent crystals included zircon, apatite, and quartz.
A transparent, prismatic apatite crystal (identified with micro Raman) is suspended in the interior of this garnet from Mozambique.
A small, rounded crystal accompanied by several elongated, slender tubes stands out in this spessartine garnet. These spindly inclusions evoke a Tim Burton-esque aesthetic.
Clusters of “silk” needles, likely rutile, intersect in a dense swarm in this spessartine garnet. These silk needles in garnet intersect at characteristic angles of 70° and 110°.
A small reflective platelet peeks through in one corner of a tsavorite garnet.
A cluster of apatite crystals, both prismatic and rounded, is a charming guest in this tsavorite garnet. The crystals were identified with micro Raman.
A spherical metallic crystal is a standout feature in its garnet host. Specimen courtesy Nomad’s.

Garnet inclusions may include mineral crystals, fluid inclusions, fractures, 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 garnet, understanding its geological history and, in some cases, determining geographic origin.

Garnet Inclusion Photomicrographs

The Hyperion garnet gallery includes microscopic features found in garnets from deposits around the world. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.

What Inclusions Can Reveal About Garnet

Inclusions are an important part of garnet identification. Their form, composition and associations can help gemologists distinguish natural garnet from synthetic and imitation materials, identify particular garnet varieties, and study the geological environment in which the garnet formed.

Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from known garnet deposits.
