Below is the chemical composition of the gem garnet species.

Garnet gem chemical formula. Y Al Cr or Fe 3. Other hydrogarnets have been reportedeg hydroandradite and hydrospessartine. Mn 3 Al 2 Si 3 O 12.

Garnet- doublet s are made of a colored glass bottom with a Garnet gemstone fused to the top of the stone. Uvarovite is the rarest of the familiar Garnets and is seldom used as a gem. X most often represents Ca Fe 2 Mn or Mg.

Fe 3 Al 2 Si 3 O 12. Most gems have a dark purplish red or reddish purple color due to Fe2 iron but some gems may appear pure red possibly due to additional chromium content. Uvarovite is a calcium chromium garnet with the formula Ca 3 Cr 2 SiO 4 3.

Typically red but can be orange green yellow purple black or brown. Mg 3 Al 2 Si 3 O 12. Ca 3 Fe 2 Si 3 O 12.

Ca 3 Al 2 Si 3 O 12. The garnet group is composed of minerals of the general formula X 3 Y 2 Z 3 O 12 where X Mg Fe 2 or Ca. Garnet is a rather complex mineral that has a general chemical formula of R3R2SiO43 where R3 is a bivalent gives up two electrons metal and R2 is a trivalent gives up three electrons metal when forming a chemical bond.

In addition to tetrahedral and octahedral sites such as those seen in spinels garnets have dodecahedral 12-coordinated sites. The X-site is 8 coordinated the Y -site is 6-coordinated octahedral and the Z-site is 4-coordinated tetrahedral. It is rarely used as a gemstone though and is most often produced for industrial and optical uses.

The members of this group intermingle with one another within limits. The origin of Loose Natural Tsavorite Green Garnet gemstone is mainly from Kenya and is most energetically focused on the Grossular varieties. It resembles and is a stone of richness and wealth.

X23Y32 Si 3 O 12. The simple chemical formula of the group is. Almandine is the most common gem Garnet.

The Garnet mineral group is compromised of isomorphous minerals identical in crystal structure and in many cases difficult to determine one from another. Blue garnets are extremely rare. The general formula for hydrogarnets would be A3B2 SiO 4 3 - x H 4 O 4 x and the general formula for an end-member hydrogarnet would be A3B2 H 4 O 4 3.

Ca 3 Al 2 SiO 4 3-x OH 4 x. Garnets have the general chemical formula A 3 B 2 Si 3 O 12 where A is a divalent cation Fe 2 Ca 2 Mg 2 Mn 2. 26012021 Of course the chemistry of garnets varies far more than the hand model can accurately demonstrate.

The color of Uvarovite is a deep chrome-green and Uvarovite is a unique Garnet being that it only comes in one color. Garnet Garnet is a more complex orthosilicate than olivine for example in which the SiO 4 tetrahedra are still independent. Gadolinium Gallium Garnet GGG Gd3Ga2GaO43 is another synthetic Garnet form.

Garnet ferrites have the structure of the silicate mineral garnet and the chemical formula M 3 Fe 5 O 12 where M is yttrium or a rare-earth ion. And Z Si.
