1, and the crystallization time of artificial garnet is short.

2. Natural garnet takes a long time to crystallize.

Second, the color permeability is different.

1, artificial garnet has bright color and good permeability.

2. The color permeability of natural garnet is very poor.

Extended data

The chemical composition of garnet is complex, and different elements form different combinations, thus forming a series of garnet families with isomorphism. The general formula is A3B2(SiO4)3, where a represents divalent elements (calcium, magnesium, iron, manganese, etc. ) and b represent trivalent elements (aluminum, iron, chromium, titanium, vanadium, zirconium, etc. ).

There are common garnets, containing chromium and iron, which are red, purple and maroon. Followed by almandine, purplish red, with inclusions in the crystal, which can be used to figure out the starlight; Garnet is light rose purplish red, which is one of the important varieties of garnet gemstones. Eclogite contains trace vanadium and chromium ions, so there is a green variety called top grade.

Crystal characteristics: Garnet family belongs to equiaxed gem. In the crystal structure, it belongs to island silicate. The common crystal forms are rhombic dodecahedron, quadrangular octahedron, hexagonal octahedron and polygon, and growth lines can be seen on the crystal surface. Aggregate is granular or massive.
