JACINTH
Miscellaneous
- Family: None
- Region: None
- Mined At: Unspecified
- Raw Mineral: Yes
- Generic: No
Notes
(Richard Willis)
Mineral, of the ideal form Zr(SiO4) with a typical empirical analysis of ZrO2 67.01%, SiO2 32.99%, with traces of U, Th, rare earths, H2O in zircon’s cirtolite variation, Y, Nb in naegite, Hf in alvite, rare earths in oymalite, and so forth.
Hardness: 7.3 Density: 4.3-4.7 Weakly soluble in acids, not in water.
Jacinth is sometimes referred to as a reddish-orange pseudo-variety of amethyst or sapphire. In fact, it is mineralogically a variety of zircon, a popular substitute for tin as an opacifier in its commercially available oxides.
