MdMaya Gems accompanies you in your search for unique and natural gemstones and invite to learn about gemstones and discover the beauty of the inclusions. The beauty is inside. 

"To those who are able to explore their secrets, precious stones relate a story as interesting as that of the huge pyramids erected by the Pharaohs at Memphis, and it would seem that their sublime internal spheres might best be called, The Fingerprints of God.” 

Edward J. Gübelin Inclusions as a Means of Gemstone Identification, 1953

Typical Inclusions in Garnets

Back to Top
Garnet Gemstone is not a single mineral, is the name of a group which has a rich variety of color: red, orange, green, yellow, purple, pink, brown and even blue.
Garnet Gemstone is the name for a group of related mineral species. The group of garnets are formed by two isomorphic series (same structure but different composition).
Typical inclusions: Solid Inclusions, healed fracture, liquid inclusions, etc. Demantoid might have eye-visible inclusions called horsetails (chrysotile fibers). Hessonite garnet often has a turbulent inner appearance and is typically heavily included.

Back to Top
The most common color of the topaz is colorless and brown, not blue. The color blue, mostly, is caused by treatment.
On the nature found colorless (white), brown, blue, yellow, orange, pink, purple and red topaz. Topaz is allochromatic, its color is caused by impurity elements or color centers (crystallographic defects).
Typical inclusions: Biphasic and Triphasic inclusions with immiscible liquids, veils, fingerprints or feathers. Solid inclusions (hematite, fluorite, etc). Solid inclusions finished “comet tail”. Needle-like rutile inclusion. Straight lines of growth.

Typical Inclusions in Aquamarine

Back to Top
Aquamarine  are usually eye-clean, (the inclusions cannot be seen with the naked eye) with great lustre and transparency.

Typical inclusions: The main inclusions are parallel “tubes” or “channels” to axis C,  solid inclusions (ilmenite, goethite, apatite, quartz, etc.), multi-phase inclusions, sometimes resembling iridescent “confeti”, healed fractures, feather or fingerprinters.

The characteristics and arrangement of the inclusions are responsible for the ASTERISM and CHATOYANCY in the aquamarine gemstone.

Typical Inclusions in Sunstone

Back to Top

Sunstone gem is a plagioclase feldspar and has a hardness of between 6 - 6.5.
Sunstone occurs in red, orange, yellow , green, colorless color.
Typical Inclusions: it is normal to find thin copper plates , hematite or goethite which are aligned and produce aventurescence (metallic effect produced by the reflection of light). The inclusions of these gemstones are absolutely awesome.

Sunstone Cabochon. Rich Golden Orange natural color with aventurescence (metallic spangled effect caused by the reflection)

Inclusion type: Aventurescence in Sunstone Cabochon 20.70 ct.  (metallic spangled effect caused by the reflection). Solid inclusions of Hematite, copper, or some other mineral.

Typical Inclusions in Clinohumite

Back to Top

Clinohumite is a fairly rare member of the family group of humite, with a hardness of 6 (Mohs' scale), usually opaque o translucent and rarely transparent. This rare orange gemstone occurs rarely in gem quality or larger than 3 ct. Clinohumite faceted quality gem has a high value

Typical Inclusions: Solid inclusions (cristals), bifasic inclusions, growth lines of different orange, healed fractures, etc.

The best quality comes from Turkey.  Gemstones over 10 ct are very rare. Inclusions are very commom. Hardness of 6  - 7 (Mohs' scale).
