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.

A group of dark rutile crystals can be viewed in this garnet from Tanzania. They were identified with micro Raman. Specimen courtesy Mark Saul.
A blue apatite crystal (identified with micro Raman) is suspended amidst a cluster of needles in this garnet from Tanzania. Specimen courtesy of Mark Saul. Fabrication courtesy of Indy Khurana.
These blue crystals stand out in their host, a garnet from Tanzania. Analysis with micro Raman revealed they are apatite. Specimen courtesy of Mark Saul. Fabrication courtesy of Indy Khurana.

This tsavorite garnet was exceptionally clean, but with magnification we were able to spot one tiny inclusion: an apatite crystal.
A cluster of diopside crystals, identified with micro Raman, stands out next to fibrous needles in this demantoid garnet.
Fibrous needles radiate from the center of this demantoid garnet.
This pyrope-almandine garnet contained an elongated rod-like crystal that micro Raman analysis revealed to be pargasite.
This tsavorite garnet host was hiding a small surprise inside: a diopside crystal that looks as though it is being supported by the finest of threads. The diopside crystal was identified with raman spectroscopy.
This tsavorite garnet contains a nicely formed apatite crystal in its depths. We confirmed the identity of this crystal with raman microscopy.

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.
