| 説明 | (8 millimeters across at its widest)---------------------------This is a synthetic gemstone called "YAG" - yttrium aluminum garnet, Y3Al5O12. The name is inaccurate, as garnet is a silicate mineral and this material has no silicon - it's actually yttrium aluminum oxide. This chemical does not exist naturally as a mineral, but is essentially corundum (Al2O3) with some of the aluminum replaced by yttrium. YAG is produced as a diamond simulant, but is softer, with a hardness between 8 and 9 on the Mohs Scale.---------------------------See info. at:en.wikipedia.org/wiki/Yttrium_aluminium_garnet |
