rutilated topaz
Topaz with yellow needle-like
inclusions of the mineral
Limonite. Rutile Topaz is very similar in appearance to
Rutilated Quartz, hence the name Rutile Topaz. However, the name is a misnomer, since unlike Rutilated Quartz which has inclusions of the mineral
Rutile, the inclusions of Rutile Topaz are not Rutile but rather Limonite.
